The Dominance and Monopolies Review: Canada


Abuse of dominance is one of the foundational provisions of Canadian competition law under the Competition Act (the Act),2 alongside cartels, mergers, vertical distribution practices and misleading advertising. Originally a criminal provision, abuse of dominance has been an administratively reviewable civil matter since 1986. It was significantly strengthened by the 2009 amendments that introduced the potential for large administrative monetary penalties (AMPs).3 Combined with increased enforcement by the Canadian Competition Bureau (the Bureau), abuse of dominance has taken on a higher level of practical importance and potential risk for firms active in the Canadian marketplace.

The abuse of dominance provisions are set out in Sections 78 and 79 of the Act. In basic terms, an abuse of dominance in Canada requires a finding by the Competition Tribunal (the Tribunal) that one or more dominant firms have engaged or are engaging in anticompetitive conduct, with the actual or likely effect of substantially lessening or preventing competition in a market. Where an abuse of dominance is established, the Tribunal can prohibit the practice, require another action to be taken or impose AMPs.

The requisite elements of an abuse of dominance have received extensive judicial consideration, and the assessment of whether a firm is dominant and whether other required elements of an abuse have been met is far from straightforward.

To provide guidance in this area, the Bureau has issued the Abuse of Dominance Enforcement Guidelines (the Guidelines),4 describing its approach to the interpretation of the statutory provisions in light of case law. The Guidelines, last updated in March 2019, explicitly supersede policy statements and several earlier guidelines, including the prior 2001 and 2012 versions of the Guidelines, as well as detailed enforcement guidelines on predatory pricing,5 guidelines specific to the telecommunications and grocery sectors, and draft guidelines specific to the airline industry.6

The Guidelines do not have the force of law and are not binding on the Tribunal, Canadian courts or even the Bureau.7 The Guidelines also emphasise that the Bureau's enforcement approach will 'depend on the particular circumstances of the matter in question', and on the discretion of the Tribunal and Canadian courts in contested cases.8 In practice, abuse of dominance in Canada turns significantly on fact-specific analysis and risk assessment. Firms that are likely to be, or to become, dominant may be subject to a higher level of potential scrutiny and exposure of their business activities if they do not adapt accordingly.

Year in review

i Enforcement in the digital economy

Recent developments reflect the Bureau's increasing focus on markets within the digital economy and innovative markets generally. In a speech given in October 2020, the Commissioner of Competition (the Commissioner) flagged the digital services industry as a key sector of the Canadian economy and stressed the need for increased enforcement.9

The need for active enforcement in the digital sector was first discussed in 'Competition in the digital age: The Competition Bureau's Strategic Vision for 2020–2024', released in February 2020.10 In this document, the Bureau undertook to expand its proactive intelligence gathering efforts and modernise its technology to better detect and stop anticompetitive activity across Canada, including through advanced analytics, artificial intelligence and other tools aimed at the digital market (e.g., advanced analytical models, algorithms and automated processes).

Consistent with its increasing focus on the digital economy over the past few years, the Bureau started taking enforcement action in this sector in areas unrelated to abuse of dominance (e.g., mergers). It has now expanded its reach to abuse of dominance. In August 2020, the Bureau announced its ongoing civil investigation into an online retail platform that operates a Canadian marketplace,11 focusing on restrictive trade practices that are impacting competition to the detriment of consumers and companies that do business in Canada.

The Bureau's initial press release on the investigation suggests that it is considering the online retail platform's conduct both as a retailer, directly competing with other online retailers, and as a retail channel, not directly competing with sellers but whose practices affect third-party sellers' ability to offer their products.

While this investigation is still in its early stages, its outcome, particularly as it relates to the platform's activities impacting third-party sellers, will likely have significant implications for other similar companies operating in the digital sector.

ii The Toronto Real Estate Board and Vancouver Airport Authority decisions

The Toronto Real Estate Board (TREB) and the Vancouver Airport Authority (VAA) decisions confirm that the abuse of dominance provisions can apply to 'gatekeepers' (i.e., firms that do not compete directly in the market they are alleged to control).

In August 2018, the Supreme Court of Canada rejected TREB's application for leave to appeal a Federal Court of Appeal decision of 1 December 2017, bringing an end to a long-running case involving the Canadian real estate industry.12

In this case, the Bureau had sought to prohibit restrictions on TREB members' provision of direct access to multiple listing service (MLS) information, such as sales inventory, selling price and broker compensation. The Bureau argued the restrictions prevented the introduction of internet-based services, such as 'virtual office websites' through which information could be made available at low cost.13 After a rehearing, the Tribunal ultimately determined that an abuse of dominance was established. Specifically, it concluded that (1) TREB substantially or completely controlled the supply of MLS-based residential real estate brokerage services in the Toronto metropolitan area, owing to its control over the MLS, a key input for competitors in the market; (2) TREB had engaged in (and continued to engage in) a practice of anticompetitive acts; and (3) the restrictions imposed by TREB had substantially prevented, and would continue to substantially prevent, competition in the supply of residential real estate brokerage services.14 This reduction in non-price competition, according to the Tribunal, included 'a considerable adverse impact on innovation, quality and the range of residential real estate brokerage services that likely would be offered' in the area absent these restrictions.

The result in TREB provides a significant clarification to the application of Section 79(1)(b) of the Act, which, as discussed in Section IV, requires that a dominant firm or firms have engaged in 'a practice of anticompetitive acts'. In the leading case interpreting this requirement, Canada Pipe,15 the Federal Court of Appeal had appeared to hold that the dominant firm must be a competitor of the firm or firms targeted by the practice, and the Tribunal in its original decision in 2013 followed this line of reasoning.16 Considering the Court of Appeal's explicit subsequent rejection of that interpretation, and the ultimate outcome of the case, TREB arguably can be regarded as a landmark in Canadian abuse of dominance analysis. Its influence is already apparent in the subsequent VAA case, as well as in the Guidelines.17

The proposition that abuse of dominance provisions apply to firms that do not compete directly in the relevant market was confirmed by the Tribunal's decision in October 2019 dismissing the Commissioner's application against the VAA, responsible for the management and operation of Vancouver International Airport, including granting physical access to the airport.18

The case involved restrictions imposed by the VAA that, according to the Bureau, decreased competition at the airport among in-flight catering companies that prepare meals for flight passengers and crew, and also provide related galley-handling services. Specifically, the Bureau alleged that while airlines that operate at the airport want greater choice of suppliers, the VAA (which is not a direct competitor) denied new suppliers willing to meet this demand access to the airport. According to the Bureau, the VAA abused its dominant position 'by excluding and denying the benefits of competition' to the in-flight catering marketplace at the airport without 'legitimate explanation to justify the substantial prevention or lessening of competition that has resulted in higher prices, dampened innovation and lower service quality'.19

In a lengthy decision dismissing the Commissioner's application, although the Tribunal determined that the VAA substantially or completely controlled the market for galley-handling services at Vancouver International Airport),20 it ultimately concluded that the VAA had not engaged in anticompetitive acts nor did its conduct prevent or lessen competition substantially or was likely to do so.

The Tribunal's decision confirms and clarifies the 'plausible competitive interest' (PCI) screen used, in the context of determining whether a firm has engaged in a practice of anticompetitive acts as contemplated by Section 79(1)(b) of the Act, to limit the scope of cases alleging abuse of dominance against gatekeepers. The Tribunal concluded that the VAA had a PCI in the relevant market because of its 'participation in the upside' of overall revenues (through its interest in concession fees), together with its ability to exclude additional suppliers from the relevant market, which distinguished the VAA from a typical upstream supplier that would suffer from a less competitive downstream market.

However, the Tribunal accepted that in excluding new entrants, the VAA could reduce the risk of finding itself in a position where it could lose one of its two full-service catering firms, thus preserving competition, choice and reliability for airlines. The Tribunal also accepted that the VAA believed its exclusionary conduct protected the airport's reputation because by maintaining two full-service catering firms, it reduced the risk of airlines experiencing significant adverse consequences because of the entry or exit of a caterer. The Tribunal held that to the extent reputational concern affected the airport's ability to compete with other airports for new routes, it constitutes a legitimate pro-competitive rationale unrelated to an anticompetitive purpose. Finally, the Tribunal also accepted that the VAA's concern that introducing new entrants could result in aeroplanes departing without sufficient or high-quality meals, was a legitimate pro-competitive rationale.

iii Recent enforcement

Active enforcement has continued in a range of other cases and recent investigations focused on:

  1. a case with a software development company regarding certain restrictive business practices in markets relating to the supply of 'all-inclusive travel packages';
  2. a large grocery retailer's dealings with its suppliers;
  3. online search and search advertising practices;
  4. a smartphone manufacturer's agreements with Canadian wireless carriers;
  5. restrictive clauses in contracts between TMX Group Limited and investment dealers;
  6. brand-name drug manufacturers' attempts to restrict access to samples needed to prove bioequivalency of generic products;
  7. the possible implications of a biological drug manufacturer's relationships with hospitals, insurers, infusion clinics and patients on biosimilar firms' ability to compete; and
  8. a national airline's low-cost carrier division's pricing policy.

The following table summarises significant recent decisions and developments.

Market definition and market power

Determining that a firm is dominant is the first of three statutory conditions that must be independently met for the abuse of dominance provisions to apply.

The statutory criteria for dominance are set out in Section 79(1)(a) of the Act, which requires a finding that 'one or more persons substantially or completely control, throughout Canada or any area thereof, a class or species of business'. Whether this statutory test is met turns on the definition of the relevant market and an assessment of the exercise of market power.

i Market definition

A 'class or species of business' and the words 'Canada or any area thereof' have been interpreted by the Tribunal to refer to the relevant product and geographical market or markets.32 Market definition focuses conceptually on the existence of substitutes for the product and geographical territory in question. It is usually determined on the basis of a 'hypothetical monopolist' test that looks at the smallest market in which a 'small but significant and non-transitory increase in price' could be profitably imposed, beginning with the product of the firm in question and the area in which it operates, and expanding the relevant market to include other products or supplier locations likely to be substituted.33

This is generally consistent with the approach taken by the Bureau in defining markets for purposes of merger analysis.34 As in the case of mergers, market definition may depend significantly on the particular features of the product and geographical markets in question. A market need not be conclusively defined to find that a firm or firms exercise market power.35

In addition to considering actual price and supply data where available, the Bureau may take into account a range of other factors in its assessment of the product and geographic market definition, including:

  1. consumer behaviour;
  2. past product or location substitution;
  3. product functional interchangeability;
  4. unique product characteristics;
  5. transportation costs and shipping patterns;
  6. switching costs;
  7. the role of distant sellers and foreign competition; and
  8. past price correlation among substitute products.36

The 2019 Guidelines specifically contemplate how to apply the hypothetical monopolist test to 'multi-sided' platforms, where demand for one side depends on use of another, and indicate that the Bureau may define the product market either as one side of the platform or as including multiple sides, depending on the case. The updated Guidelines also consider the challenges that may arise in the application of this test where services are offered at a 'zero-monetary price' (e.g., to attract users to a multi-sided platform), and indicate that in these cases, the Bureau may focus on 'qualitative indicators of substitutability' rather than seeking to analyse whether a hypothetical monopolist would find it profit-maximising to decrease a relevant non-price dimension of competition by a small but substantial amount for a non-transitory period of time.

More generally, the updated Guidelines retain ample flexibility for the Bureau to define one or more product markets. For instance, the Bureau 'may consider it appropriate to define markets in reference to particular types of purchasers in certain circumstances, such as where sellers engage in price discrimination between different sets of buyers', or by referring to 'a particular level of the supply chain'. Moreover, the Bureau 'may consider it appropriate to analyse several different (or potentially different) product markets together for the purposes of market definition'. This appears to reflect recent case law, such as Softvoyage, in which more than one relevant market was identified. Additionally, the Guidelines specifically contemplate the possibility of analysing several geographic markets together.

ii Market power

The words 'substantially or completely control' in the context of the abuse of dominance provisions have been held by the Tribunal in TREB to contemplate a substantial degree of market power. Such market power confers 'considerable latitude to determine or influence price or non-price dimensions of competition' in a market, and may be reflected in the power to exclude.37 The Guidelines, as updated in 2019, take this approach, indicating that market power (the assessment of which takes into account both pre-existing market power and the market power derived from allegedly anticompetitive practices) may be reflected in the power to exclude; that is, an ability to restrict the output of other existing or potential market participants and 'thereby profitably influence price'. Here again, the updated Guidelines reserve discretion for the Bureau, indicating that the assessment of whether a firm holds a substantial degree of market power may depend on 'the body of relevant information and/or documents on the whole' and noting that the 'exact nature of the Bureau's analysis and the weight accorded to any particular piece of information or document will depend on the circumstances of the case'.38

The Guidelines note that, while market power can be measured through direct factors such as high profit margins or 'supracompetitive profitability or pricing', these factors can present analytical issues and may be inconclusive. The more common analysis will, therefore, use indirect indicia of market power that suggest the extent to which a firm or firms will be constrained from implementing anticompetitive price increases, either owing to existing competition or likely competitive entry. Indirect indicia considered by the Bureau include the 'structural characteristics' of a market (such as market shares and barriers to entry) and the effects of anticompetitive acts and countervailing power from customers or suppliers.

Notably, in a clear nod to the outcome of the TREB case, the updated Guidelines expressly contemplate that a firm 'that does not compete in a market may nonetheless substantially or completely control that market'. In such cases, the power to exclude competitors will often feature prominently in the Bureau's analysis, whereas market shares or supracompetitive profits may not be as central. This update to the Bureau's approach presumably is the reason for which the 2019 version of the Guidelines also de-emphasises a market share safe harbour, as discussed below.

iii Market share

There is no statutory threshold for market share that will necessarily give rise to market power, nor a statutory safe harbour below which a firm will not be considered dominant. However, market share is 'usually a necessary, but not sufficient'39 condition of finding market power, and will ordinarily be considered together with other factors. Market share may be measured on the basis of revenues, unit sales, sales or production capacity or natural resource reserves, depending on which 'best reflects the current and future competitive significance of competitors'.40 In addition to the actual share, the Bureau will consider the distribution of market share among a firm's competitors, as well as market share fluctuations.

Although the Bureau has historically taken the position that a single firm market share below 35 per cent will be considered unlikely to give rise to a finding of market power, the 2019 Guidelines state only that a market share below 50 per cent will 'generally only prompt further examination' if it is believed that the anticompetitive conduct is likely to result in increased market share in a reasonable period.41 On the other hand, a single firm market share above 50 per cent (or a combined share above 65 per cent, in the case of joint dominance) will 'generally prompt further examination'. In the Tele-Direct case, the Tribunal held that where market share is 80 per cent or greater, it will look for 'extenuating circumstances' and 'generally, ease of entry' to outweigh a prima facie finding of market power.42 In practice, contested abuse of dominance cases both before and after Tele-Direct have involved market shares of 80 per cent to 100 per cent, usually in highly concentrated markets.

iv Barriers to entry; other factors

As market share is not determinative of market power, the Bureau will also consider the barriers to entry that may be present in the market, including:

  1. sunk investments (e.g., in equipment, infrastructure or research and development);
  2. regulatory barriers;
  3. whether the market is mature or depends on economies of scale or scope;
  4. network effects; and
  5. availability of scarce resources or inputs.

Market entry despite barriers to entry must be likely, timely and sufficient to prevent or discourage the exercise of market power.

The Guidelines recognise that, in some instances, customers will constrain market power, for example, through vertical integration or by encouraging entry or expansion of competitors. Markets that undergo rapid technological change or innovation, or some other material form of change, may warrant different consideration if this permits new or existing competitors to overcome the exercise of market power.

v Joint dominance

The words 'one or more persons' in Section 79(1)(a) of the Act explicitly recognise that two or more firms may have joint dominance. As explained in the Guidelines, the Bureau's approach to joint dominance is essentially similar to that for single firm dominance except that it is also necessary to find that control of the market is exercised jointly.

For purposes of the criminal conspiracy provisions of the Act, 'conscious parallelism', in itself, does not constitute an agreement, and the Bureau adopted this position in prior (2001) Abuse of Dominance Enforcement Guidelines, which also described factors that could be used to infer joint action in the civil context. The 2019 Guidelines simply state that '[s]imilar or parallel conduct by firms is insufficient' to establish joint dominance, and offer no further insight into the extent of joint conduct – or maximum level of intra-group competition – required to find joint control of the market. The threshold test for joint dominance has never been considered by the Tribunal as, although the Bureau has commenced three significant joint dominance cases, all have settled prior to a contested hearing.43

In addition to the application of the abuse of dominance provisions to joint dominance, since 2010 it has been possible to address coordinated conduct under Section 90.1 of the Act, a civil provision that applies to agreements between competitors that substantially lessen or prevent competition.44

vi Attempted monopolisation

In contrast to the US Sherman Act, attempted monopolisation is not caught by the abuse of dominance provisions in Canada. The existence of market power at the time anticompetitive conduct is engaged in is implicit in the formulation of the statutory test, and would prohibit an application to the Tribunal on the basis of anticipated market power. The 2019 Guidelines, moreover, no longer refer to the possibility that the Bureau may investigate the conduct of a firm that is expected to acquire market power as a result of the allegedly anticompetitive conduct 'within a reasonable period of time'.45

Nonetheless, the updated Guidelines suggest that the Bureau may contemplate, if not necessarily 'attempted' monopolisation, the possible acquisition of market power where none existed previously. For example, the Guidelines do refer to anticompetitive conduct that permits the exercise of 'new or increased market power'.46 More generally, the post-TREB updates to the Guidelines (including, in particular, the Bureau's consideration of dominance by firms that do not compete directly in the relevant market or markets, and of the ability to exclude, as well as the de-emphasising of market shares) suggest that the Bureau may apply a nuanced and potentially broad interpretation of monopolisation.


i Overview

Dominance itself is not proscribed in Canada. For an abuse of dominance to be found, two other statutory conditions in addition to market power must be met. The first of these requires that the dominant firm or firms have engaged or are engaging in a 'practice of anticompetitive acts', as set out in Section 79(1)(b) of the Act. The second is an effects analysis of whether the practice has had, is having or is likely to have the effect of preventing or substantially lessening competition in a market, as set out in Section 79(1)(c). While apparently similar and often assessed on the basis of the same evidence, these are conceptually distinct tests.

Practice of anticompetitive acts

Although an illustrative list of 'anticompetitive acts' is provided in Section 78 of the Act, the list is not exhaustive, and in practice, the abuse of dominance provisions can apply to a wide range of anticompetitive conduct.

Whether an act will be considered 'anticompetitive' depends on the limiting principle of whether it has an intended negative effect on a competitor that is 'predatory, exclusionary or disciplinary'.47 This does not necessarily require subjective intent, and the Tribunal has held that intent can be inferred from the reasonably foreseeable consequences of the conduct or the circumstances in which it is undertaken.48

Further to the ultimate result in the TREB case, the Guidelines, as updated in 2019, take the position that 'certain acts not specifically directed at competitors could still be considered to have a predatory, exclusionary, disciplinary or some other anticompetitive purpose'.49 This interpretation would encompass 'facilitating practices' that do not themselves harm a competitor but permit coordination. It is broader than the interpretation that appeared to have been applied in the earlier Canada Pipe case, in which the requirement that an anticompetitive act be intended to harm a competitor was essential.50 Additionally, as clarified in VAA, in cases where the dominant firm does not compete in the market it is alleged to control, the Bureau (and the Tribunal) will consider whether the firm has a plausible competitive interest when determining whether it has engaged in a practice of anticompetitive acts.

Where anticompetitive intent has been inferred, it is possible to rebut a presumption that the purpose of conduct is anticompetitive by establishing that the conduct had a valid business purpose or justification. In Canada Pipe, it was held that a business justification must have a 'credible efficiency or pro-competitive rationale' and be one that 'relates to and counterbalances the anticompetitive effects or subjective intent of the acts'.51 However, the Guidelines take a broader view that a business justification, while not a defence, could be anything that provides an 'alternative explanation for the overriding purpose of the conduct'.52

Further, the VAA decision clarified that as a matter of law, the regulated conduct doctrine (RCD) does not apply as a defence in Section 79 cases because, inter alia, Section 79 does not contain the 'leeway' language required to allow the RCD to be invoked and, in the VAA's case, there was no statute, regulation or other subordinate legislative instrument that required, directed, mandated or authorised it, expressly or by necessary implication, to engage in the conduct. That said, the Tribunal did, however, confirm that compliance with a statutory or regulatory requirement may nonetheless constitute a legitimate business justification for conduct that is potentially anticompetitive.

A 'practice' of anticompetitive acts under the abuse provisions generally requires more than a single act, but could be met by a single act that has an ongoing or systemic effect or a 'lasting impact' in a market.53 A practice may also consist of different forms of anticompetitive conduct,54 not only repeated use of the same conduct, and can therefore in theory include otherwise innocuous conduct, if used in an anticompetitive manner in combination with other anticompetitive practices.

Substantial lessening or prevention of competition

An abuse of dominance will be subject to a remedy under the Act only if there is an actual or likely substantial lessening or prevention of competition. In principle, this test concerns competition rather than individual competitors.55

The prevailing test was formulated in Canada Pipe, and recently affirmed in TREB, as well as in the context of the evaluation of mergers under the Act.56 It is a 'but for' test that seeks to determine if it is likely that there would be substantially greater competition (past, present or future) in the absence of the impugned conduct.

As was the case prior to Canada Pipe, the test considers whether a practice contributes to the creation, preservation or enhancement of market power, which will be assessed in terms of whether there is substantial effect on market entry or expansion by new or existing competitors. However, in contrast to the test prior to Canada Pipe, it is a comparative, relative assessment, rather than a consideration of whether the absolute level of competition is substantial or sufficient.57 The Guidelines indicate that the Bureau will also consider factors such as whether, but for the practice, monetary prices would be lower, product quality, service, innovation or choice would be greater, or switching between products or suppliers would be more frequent.58 The prior (2012) version of the Guidelines listed similar factors but qualified them by describing the 'but for' scenarios as 'substantially' different, which may suggest that the 2019 Guidelines broaden the potential situations in which the Bureau may look into any given practice.59

ii Exclusionary abuses

The Act enumerates several practices in Section 78 of the Act that relate to the exclusion of a competitor, including:

  1. margin squeezing by a vertically integrated supplier;
  2. acquisition by a supplier of a customer;
  3. pre-emption of scarce facilities or resources;
  4. adoption of non-compatible product specifications; and
  5. exclusive dealing.60

The Guidelines specify that the list above is non-exhaustive and also reference tying and bundling and activities that increase customer switching costs. Moreover, the 2019 Guidelines refer more generally to other activities that 'increase a rival's costs', as was the case in the prior version, and activities that may 'reduce their revenues'.61

The Tribunal and Canadian courts have also recognised numerous other exclusivity abuses in case law, including:

  1. meet-or-release and most-favoured nation clauses;62
  2. rights of first refusal;63
  3. automatic price increases;64
  4. long-term contracts;65
  5. negative option automatic renewal provisions;66
  6. costs or penalties, such as liquidated damages or excessive fees to switch suppliers, return goods or otherwise terminate contracts early;67
  7. the acquisition of competitors and inclusion of non-compete clauses in the acquisition agreements;68
  8. various kinds of loyalty or fidelity rebates,69 including discounts and allowances in exchange for the use of the supplier's logo and name;70
  9. exclusive networks;71
  10. market allocation;72
  11. in the real estate services cases, the use of a database in a way that could be exclusionary;73 and
  12. in the airport case, denying new catering suppliers access to an airport.74

iii Discrimination

The Act formerly contained per se criminal prohibitions against price discrimination and predatory pricing. When price maintenance was decriminalised with the repeal of those provisions in 2009, it was acknowledged that this conduct would remain subject to review under the abuse of dominance provisions where the conditions of Section 79 were met.75

The Act enumerates several examples of discriminatory or predatory conduct, including freight equalisation, introducing fighting brands selectively and temporarily, buying up product to prevent price erosion, and selling articles below acquisition cost.76 Prior cases have also considered the intimidation of competitors and customers through spurious or threatened litigation,77 cross-subsidisation78 and predatory pricing generally.79

The Guidelines provide that in the context of predatory pricing conduct, the Bureau will assess whether the predatory price is sufficient to cover the average avoidable (i.e., variable) costs of providing a good or service, taking into account whether competitors could match the price without incurring a loss, and whether an allegedly predatory price is being offered to meet competition.80

iv Exploitative abuses

As discussed above, the 2019 Guidelines appear to take a broad and flexible approach to the interpretation of anticompetitive acts. In particular, they do not explicitly exclude excessive pricing or similar exploitative abuses. Nonetheless, in principle, the Act does not prohibit such practices, except to the extent that they have an exclusionary, disciplinary or predatory purpose and likely effect.

Remedies and sanctions

i Sanctions

Since 2009, the Tribunal has had the discretion, in addition to ordering behavioural or structural remedies, to impose AMPs of up to C$10 million in the first instance or C$15 million for a 'subsequent order'.81

Pursuant to the Act, the Tribunal is required to consider various factors in determining the amount of an AMP, including the affected sales, actual or anticipated profits, the dominant firm's financial position, its history of compliance and 'any other relevant factor'.82 An unpaid AMP is a debt owed to the Crown and recoverable in any court of competent jurisdiction.

Although the stated purpose of AMPs in the Act is compliance and not punishment,83 the constitutionality of AMPs has been challenged in other contexts on the basis that they are punitive and therefore warrant the same procedural protections as criminal penalties.84 To date, the water heater rental industry cases (Reliance and Direct Energy) are the only ones in which AMPs have been sought by the Bureau and ultimately imposed.85

ii Behavioural remedies

The most basic remedy under Section 79 is an order prohibiting the continuation of a practice of anticompetitive acts. In addition, or as an alternative, the Tribunal has broad discretion to make any other order required to restore competition, where a prohibition order alone is not likely to be sufficient to restore competition in the market.86 Both consent agreements and prohibition orders can theoretically be imposed for an indefinite period.87

An interim order may be issued, on application by the Bureau on an ex parte basis, where the Tribunal finds that injury to competition cannot be adequately remedied by a later order, or in certain other specific circumstances, is likely to occur in the absence of the order.88

iii Structural remedies

The Tribunal's authority to make a restorative order explicitly extends to an order to divest assets or shares, if reasonable and necessary to overcome an abuse of dominance, although to date divestiture has never been ordered under Section 79.


The Monopolistic Practices Directorate of the Bureau's Mergers and Monopolistic Practices Branch investigates potentially anticompetitive business practices, such as abuse of dominance and restrictive vertical trade practices, as well as certain types of anticompetitive agreements or arrangements.89

Obtaining an order for a remedy under the abuse of dominance provisions in principle requires an application by the Commissioner of Competition to the Tribunal, a specialised competition court with judicial and lay members that hears and decides non-criminal matters under the Act.90 Cases before the Tribunal are subject to rules of procedural practice, which, inter alia, provide for documentary, written and oral discovery on a relevance standard.91 Decisions of the Tribunal may be appealed to the Federal Court of Appeal, and ultimately to the Supreme Court of Canada. Courts may refer matters back to the Tribunal for redetermination.

However, it is increasingly common for alleged abuses of dominance to be investigated and initially challenged outside the formal Tribunal process with a view to seeking a negotiated resolution. Negotiated settlements are then recorded in a 'consent agreement', which is registered with the Tribunal and, once registered, carries the legal force of an order of the Tribunal.92 Firms that volunteer to make changes in their business practices are generally required to formalise these commitments in a consent agreement.93

Consent agreements must be 'based on terms that could be the subject of an order of the Tribunal', but consent agreements filed with the Tribunal are not subject to its substantive oversight; nor are full details of the conduct leading to the agreement made public. Given the availability of consent agreements, abuse of dominance investigations often settle before reaching the contested hearing stage. On the other hand, this framework has been observed to be one in which respondents may '“dig in”, or at least protract settlement discussions, to avoid a restrictive consent agreement'.94

The Act provides the Bureau with numerous tools to investigate alleged abuses of dominance, including the ability to obtain a judicial order under Section 11 of the Act to compel oral examination, document production or a written response to questions, where the Bureau believes grounds may exist for an order. Section 11 orders can extend to affiliates outside Canada of a Canadian corporation that is subject to the order, and can also be used to obtain information from third-party customers, suppliers and competitors. The Bureau has increasingly made use of this tool to compel production in recent enforcement activity, such as the inquiries involving Loblaw, the smartphone industry, the VAA and online search and advertising, and in several recent cases it has highlighted its reliance on third parties in particular.95 The Bureau can also obtain a warrant to enter and search premises and seize documents, or, in 'exigent' circumstances, exercise these rights without a warrant.96

Various procedural limitations are set forth in statute. Applications for remedies must be brought to the Tribunal no later than three years after a practice has ceased.97 The Commissioner may not bring an application under both the abuse of dominance provisions and either the criminal conspiracy provisions or the civil price maintenance, competitor collaboration or substantive merger provisions.98 However, the Bureau may, and often does, bring applications under both the abuse of dominance provisions and provisions relating to other vertical trade practices. Moreover, it is not uncommon for an investigation under the abuse provisions to immediately precede or follow the Bureau's examination of the same firm under other provisions. For instance, the Bureau's inquiry into certain practices of the grocery retailer Loblaw, based on potential abuse of dominance concerns, immediately followed its review of Loblaw's acquisition of a large pharmacy retailer (during which, according to the Bureau's statement, it uncovered evidence that certain of the grocery retailer's policies 'may have been implemented for an anticompetitive purpose'). In turn, an investigation into alleged price-fixing of bread products among Loblaw and other retailers appears to have immediately followed the abuse inquiry.99

In practice, the Bureau also frequently collaborates with its international counterparts. For instance, it consulted with the US Federal Trade Commission and the European Commission in the course of its investigation into online search and advertising practices, and indicated that it would continue to closely follow international investigations into similar alleged conduct. The Bureau has similarly referenced communications with foreign counterparts in the recent smartphones inquiry.

Private enforcement

There is no private right of action to obtain remedies for abuse of dominance in Canada. Only the Commissioner may bring applications or register consent agreements with the Tribunal.

There is also no statutory right to obtain damages as a result of a finding of an abuse of dominance, although under Section 36 of the Act a private right of action is available where an order of the Tribunal has been violated.100

Attempts by private litigants to bring cases on the basis of civil conspiracy or torts alleging an abuse of dominant position have not been recognised for the reason that, unlike the criminal provisions, the civil provisions of the Act are presumptively lawful unless and until an order has been granted by the Tribunal.101

However, Section 103.1 of the Act does allow private parties to apply for leave to bring applications before the Tribunal under the refusal to deal (Section 75), price maintenance (Section 76), and exclusive dealing, tied selling and market restriction (Section 77) provisions of the Act, where the underlying requirements of those sections are met. While the remedies available under those provisions do not include AMPs or damages, and while it is costly to bring an action, private litigants could in theory use Section 103.1 to prohibit certain conduct that might otherwise be pursued as an abuse of dominance, or to draw attention to related abuse of dominance concerns, providing private parties with a 'back door' method of privately challenging abuse of dominance.102

Private parties are also entitled to file a complaint with the Bureau with regard to the abuse of dominance provisions. Consumer and competitor complaints are a primary source of leads for Bureau investigations.

Future developments

The continued focus on markets within the digital economy and innovative markets generally, as well as the outcome of the current investigation into an online retail platform that operates a Canadian marketplace, are likely to be of particular relevance for the law of abuse of dominance in Canada in the coming year.

12 Toronto Real Estate Board v. Commissioner of Competition (TREB), 23 August 2018, Case 37932, dismissing application for leave to appeal 2017 FCA 236. The TREB case followed an earlier, successful challenge against the Canadian Real Estate Association (CREA) arising from allegations that CREA and its members had used their control of a multiple listing service (MLS) and related trademarks to impose exclusionary restrictions that inhibited or prevented fee-for-service, flat-fee and other 'reduced service' models from effectively competing in the residential real estate services market. The CREA case was resolved by way of a consent agreement filed with the Tribunal in 2010 that prohibits CREA from adopting, maintaining or enforcing discriminatory rules for a period of 10 years (The Commissioner of Competition v. The Canadian Real Estate Association, Consent Agreement, CT-2010-002:

13 Real estate boards and associations in other Canadian jurisdictions and the United States typically allow their members access to, and use of, their MLS information to provide internet-based services.

14 Among other considerations, the Tribunal in its April 2016 decision found that the restrictions substantially reduced the degree of non-price competition in the supply of MLS-based residential real estate brokerage services, relative to the degree that otherwise would likely exist.

15 Canada (Commissioner of Competition) v. Canada Pipe Co, 2006 FCA 233 (Federal Court of Appeal). As leave to appeal the Court of Appeal's decision to the Supreme Court of Canada was denied, the Court of Appeal decision is a binding precedent.

16 In the initial decision, the Tribunal pointed in part to the Court of Appeal's observation in Canada Pipe that eight of the nine examples of anticompetitive acts enumerated in Section 78 of the Act describe harms against competitors, and harm to a competitor could be implied in the ninth example. It also noted that a proviso in Section 79(4) implies that the dominant firm must compete in the market. These provisions are further discussed in Section IV.

20 The Commissioner also argued that there was a separate airside access market. While the Tribunal agreed, it ultimately concluded that nothing turned on it. The Tribunal determined that the Vancouver Airport Authority (VAA) controlled the galley-handling services market by virtue of its control over a critical input to that market (airside access).

26 According to the Bureau, the company is dominant in both the market for 'content management' and the market for 'online distribution' software. Specifically, it was alleged that after a majority of tour operators adopted Softvoyage's content management software, the company used exclusivity clauses in its contracts requiring those tour operators to only use Softvoyage's distribution software. According to the Bureau's position statement, Softvoyage also prohibited tour operators from 'extracting or using their own data managed in Softvoyage's content management software'.

29 As reported in the media; for example, CBC News, 'Competition Bureau checks WestJet's discount airline Swoop for predatory pricing' (12 December 2018), online: In previous investigations relating to air passenger and cargo services in Northern Canada, the Bureau similarly considered, inter alia, possible predatory pricing practices under the abuse of dominance provisions.

32 Canada (Director of Investigation and Research, Competition Act) v. NutraSweet Co (1990), 32 CPR (3d) 1.

33 The benchmark for 'significant' and 'non-transitory' is a 5 per cent increase in price, sustained over a one-year period. The relevant price is that which would exist in the absence of the anticompetitive acts (often not the current price). The 'price' can include not only the nominal price, but also qualitative factors, such as product quality, choice, service, support or innovation.

34 See Competition Bureau, Merger Enforcement Guidelines (2011):

35 One distinction between the two approaches is the Bureau's acknowledgment, in the abuse of dominance analysis, of a potential 'overly broad product market definition' if current prices – that is, price levels where market power has already been exercised – are taken into account (the 'cellophane fallacy'). See Guidelines, Section 2.1.

36 Guidelines, Sections 1A and 1B.

40 Guidelines, Section 1C.

41 Despite the removal of the 35 per cent threshold in the updated Guidelines, the 50 per cent threshold nonetheless remains generally consistent with the long-standing finding of the Tribunal in the Laidlaw case that a market share below 50 per cent would not lead to a prima facie finding of dominance. Canada (Director of Investigation and Research) v. Laidlaw Waste Systems Ltd (1992), 40 CPR (3d) 289.

42 Canada (Director of Investigation and Research) v. Tele-Direct (Publications) Inc (1997), 73 CPR (3d) 1. Separately, in a case involving a sole supplier, the Tribunal presumed market power in the absence of 'evidence that there [were] no barriers to entry'; Director of Investigation and Research v. D&B Companies of Canada Ltd (1995), 64 CPR (3d) 216.

43 Canada (Director of Investigation & Research) v. Bank of Montreal (1996), 68 CPR (3d) 527; Canada (Director of Investigation & Research) v. AGT Directory Ltd [1994] CCTD No. 24; Canada (Commissioner of Competition) v. Waste Services (CA) Inc and Waste Management of Canada Corporation, Consent Agreement, CT-2009-003. However, in the 2009 Waste Services case, the Bureau's allegations against two commercial waste firms appear to have been based on parallel conduct combined with high combined market share of greater than 80 per cent. The firms in question both used long-term contracts that imposed highly restrictive terms on customers, such as automatic renewal clauses and severe penalties for early termination; the Bureau did not suggest that the challenged conduct involved any coordination or agreement.

44 Some commentators foresee a complementary role for the provisions, with Section 79 targeting conduct that reduces competition outside the oligopoly, and Section 90.1 targeting competition between the oligopoly members. See M Aitken and E Davis, 'The Changing Regulation of Canadian Oligopolies: Complementary Enforcement Roles for Section 90.1 and Joint Dominance', Conference Paper, American Bar Association Section of Antitrust Law Spring Meeting, 12 April 2013. Moreover, as noted in Section VI, the responsibilities of the Monopolistic Practices Directorate cover both abuse of dominance and certain types of anticompetitive agreements or arrangements.

45 This was expressly contemplated in the prior (2012) version of the Guidelines, Section 2.3.

46 Guidelines, Section 3 (describing conduct that 'lessens' competition). Elsewhere, the Guidelines refer to impugned practices causing 'a materially greater degree of market power to exist than in the absence of the practice', without specifying whether this would necessarily exclude an acquisition of new market power.

50 The Tribunal's initial decision in TREB also arguably foreclosed the broader interpretation. However, the Tribunal's later ruling upon reconsideration, as upheld by the Court of Appeal, leaves open the possibility that a range of acts not specifically directed at one's competitor may constitute 'anticompetitive acts'.

55 The Act does, however, require that the analysis take into account whether an impugned practice results from a market participant's 'superior competitive performance', which could be a legitimate cause of a relative decrease in competition (Section 79(4)).

56 Tervita Corporation v. Canada (Commissioner of Competition), 2015 SCC 3. In its decision of 22 January 2015, the Supreme Court of Canada considered whether, but for the merger, the acquired party would likely have entered the relevant market as a competitor.

89 Following the internal restructuring within the Bureau that became formally effective on 1 April 2015, the Mergers and Monopolistic Practices Branch now combines the Mergers Directorate, responsible for merger review, and the Monopolistic Practices Directorate. The Mergers Directorate and Monopolistic Practices Directorate were formerly known as the Mergers Branch and Civil Matters Branch respectively. Separately, the Cartels and Deceptive Marketing Practices Branch is focused on cartels and deceptive business practices.

95 For instance, the online search and advertising matter, which was a complaint-driven inquiry, involved extensive consultations with industry and economic experts, and interviews with a range of market participants. Similarly, in the Softvoyage case, the Bureau gathered information from multiple sources, including tour operators, travel agencies, industry associations, past and potential competitors and 'businesses offering similar products and services in foreign markets'. The Bureau has indicated that in the inquiry involving biologic and biosimilar drugs (discontinuation announced in February 2019), it 'interviewed key market participants, including pharmaceutical manufacturers, public and private insurers, hospitals, physicians, infusion clinic networks and trade associations, while also gathering relevant records from many of these parties'. In some cases, these communications may be conducted informally and voluntarily, as the Bureau does not always specify whether it relied on its formal powers under Section 11 in engaging third parties.

99 These allegations are outlined in court documents relating to the inquiry concerning alleged activities of Canada Bread Company, Limited; Weston Foods (Canada) Incorporated; Loblaw Companies Limited; Wal-Mart Canada Corporation; Sobeys Incorporated; Metro Incorporated; Giant Tiger Stores Limited and other persons. The case has also been reported in the media. See, for example, CBC, 'Bakers, grocers met to reach deals on bread prices, competition watchdog alleges' (1 February 2018):

100 Section 36 of the Act applies to breaches of the criminal provisions of the Act; a breach of an order of the Tribunal is a criminal offence.

101 For example, Chadha v. Bayer Inc (1998), 82 CPR (3d) 202 (Ont Gen Div). However, in an action against TREB and CREA and their directors and officers alleging in part that they had breached the terms of CREA's consent agreement, the Court of Appeal in refusing a motion to strike the statement of claim found that a reasonable cause of action was disclosed (Dale v. Toronto Real Estate Board, 2012 ONSC 512).

102 In several past refusal-to-deal leave applications, the plaintiffs alleged (or implied) that the defendant suppliers were dominant. See, for example, Barcode Systems Inc v. Symbol Technologies Canada ULC; Allan Morgan and Sons Ltd v. La-Z-Boy; Mrs O's Pharmacy v. Pfizer; Paradise Pharmacy Inc v. Novartis; Broadview Pharmacy v. Wyeth; Nadeau Ferme Avicole Limitee/Nadeau Poultry Farm Limited v.
