The Private Competition Enforcement Review: Canada

Overview of recent private antitrust litigation activity

i No damages claims for buy-side agreements

In 2021, Canadian courts confirmed that the Competition Act does not allow for buy-side conspiracy claims in a pair of quintessentially Canadian class action decisions.

In Latifi v. TDL Group Corp,2 the British Columbia Supreme Court struck pleadings alleging that Tim Hortons had breached the Competition Act's criminal conspiracy provisions by including 'no-hire' clauses in its franchise agreements, which barred franchisees from hiring employees from other Tim Hortons locations.

Similarly, in Mohr v. National Hockey League,3 the Federal Court refused to permit a pleading amendment alleging that the National Hockey League and various minor hockey leagues had conspired to limit the ability of hockey players to negotiate and play with teams in the NHL, and further conspired to impose unreasonable contractual terms on minor hockey players.

In both cases, the courts found that the criminal statutory conspiracy provision (one of the few provisions of the Competition Act whose breach permits a civil claim for damages) only applied to hardcore cartel agreements (such as price-fixing and market allocation), which are unambiguously harmful to competition. The courts held that the criminal provision does not apply to buy-side agreements among competitors, which, under certain circumstances, could be pro-competitive.

ii Ontario amends class proceedings legislation

In 2020, the government of Ontario (the leading class action jurisdiction in Canada) amended its class proceedings legislation4 to implement a series of largely defendant-friendly changes to its class actions regime.

Most significantly, the amendments impose a stricter test for class action certification, requiring class counsel to demonstrate that a class action would be superior to all reasonably available means to determine the entitlement of class members to relief, and demonstrating that questions or fact and law common to the class members predominate over any questions affecting only individual class members.5

The amendments also include provisions to attempt to limit overlapping multi-jurisdictional class actions among Canadian provinces, allowing the Ontario court to grant remedies that would streamline the overall prosecution of claims being advanced, which could include granting an order staying the class action in Ontario.6

Settlements will be subject to greater scrutiny under the new class actions regime, with class counsel required to make full and frank disclosure covering certain prescribed factors intended to assist the court in assessing the fairness of a proposed settlement.7

Finally, the amendments introduce certain procedural modifications, including encouraging early motions for dismissal, where appropriate,8 enhancing defendants' rights to appeal certification decisions,9 and streamlining contested motions for carriage between rival plaintiff firms.10

The changes took effect on 1 October 2020 and apply only to class actions commenced after that date. Pre-existing class actions remain subject to the provisions as they existed on 30 September 2020.

iii Supreme Court clarifies price-fixing class actions

In 2019, the Supreme Court of Canada delivered the most significant Canadian competition law decision in several years in Pioneer Corp v. Godfrey.11 Godfrey concerned an alleged price-fixing conspiracy in the market for optical disk drives. In its decision, the Supreme Court resolved many open questions in Canadian competition law jurisprudence.

First, the Court in Godfrey held that, to certify a price-fixing class action by indirect purchasers, class counsel need only present evidence at the certification hearing of a credible or plausible expert methodology demonstrating that loss passed through to the indirect purchaser level generally. It is not necessary for class counsel to put forward expert methodology to demonstrate injury to each individual member of the class.

Second, the Court held that, for a trial judge to employ the aggregate damages provisions of class proceedings legislation, he or she would either need to be satisfied that all class members suffered a loss or be able to distinguish between those class members that did, and did not, suffer loss, to avoid providing compensation to individuals that suffered no loss.

Third, the Court determined that 'umbrella purchasers' are able to assert a viable cause of action against members of a price-fixing conspiracy. Umbrella purchasers are purchasers that did not buy a price-fixed product from an alleged conspirator, either directly or indirectly (that is, as part of a vertical distribution chain); they bought it from firms that are not part of the conspiracy or through distribution chains descending from those firms. Class counsel typically argue that umbrella purchasers have a claim against conspirators because the alleged conspiracy created an umbrella of supra-competitive prices, enabling non-cartel members to raise prices, causing their customers to pay an overcharge. The Supreme Court has now opened the path for such claims to proceed to be tested on the evidence at trial.

Fourth, the Court held that the Competition Act does not constitute an exhaustive 'complete code' for plaintiffs who have suffered injury in a price-fixing action. Instead, it remains open for plaintiffs to also assert common law or equitable causes of action for the price-fixing conduct, such as claims of common law conspiracy or unjust enrichment.

Fifth, the Court held that the statutory two-year limitation period to commence a civil action contained in the Competition Act is subject to, and can be extended by, the principle of discoverability.

General introduction to the legislative framework for private antitrust enforcement

Like most competition regimes, Canada's Competition Act12 deals with three broad areas: coordinated conduct among competitors, unilateral conduct by firms with market power and mergers. Somewhat unusually, the Competition Act also deals with a variety of marketing practices, such as false advertising.

The Competition Act applies a mix of criminal and civil (administrative) approaches to the areas it covers, as well as both public and private remedies.

Private actions for damages are only available for breaches of the Competition Act's criminal provisions. The key criminal provisions are conspiracies to fix prices, allocate markets or reduce output,13 bid rigging14 and false advertising.15

Importantly, unilateral conduct by firms with market power, such as abuse of dominance,16 exclusive dealing,17 tied selling18 and refusal to deal,19 are not subject to criminal sanction. In fact, they are not even prohibited unless they cause a substantial lessening or prevention of competition, in which case the Competition Tribunal can prohibit the conduct. Agreements between competitors that are not hardcore cartels (such as buy-side agreements)20 or price maintenance are subject to the same treatment.

Section 36 of the Competition Act creates a civil cause of action for damage caused by breaches of the criminal provisions of the Competition Act.21 To succeed, the plaintiff must prove that the defendant committed a criminal offence under the Competition Act, and that he or she suffered damage caused by the criminal offence. The standard of proof is on a balance of probabilities.22

A conviction is, in the absence of proof to the contrary, sufficient to prove that the defendant committed the offence.23 The plaintiff must show actual damage, and that the damage was caused by the offence.24

Section 36 itself specifies two remedies: damages and costs. The amount of damages is limited to the actual loss suffered by the plaintiff, plus the costs of investigation and of the proceeding.

Actions under Section 36 are subject to a two-year limitation period that commences on the last day on which the offence was engaged in,25 or from the day on which criminal proceedings were finally disposed of. This two-year limitation period is subject to the principle of discoverability, and will not run so long as the conduct remains undiscovered by the plaintiff.26

Both direct and indirect purchasers can sue and recover damages for price-fixing,27 as can umbrella purchasers.28

Section 36 actions can be brought in the superior courts of any province, as well as the Federal Court of Canada.29 They can be structured as class actions under the class proceedings statutes or rules in most Canadian provinces, as well as the Federal Court. In Ontario, for example, the Class Proceedings Act, 199230 provides for certification of class actions, and several other provinces have similar legislation.31 Historically, plaintiffs typically started at least three class actions for each case: one in Quebec, for a class of consumers and small businesses; one in British Columbia, for British Columbia consumers and businesses; and a national class in Ontario covering Ontario and the rest of the country. In 2018, British Columbia changed from being an opt-in class action regime for out-of-province class members to being an opt-out jurisdiction for such class members. It remains to be seen whether this changes the filing strategy among the plaintiff class action bar going forward.32 In 2020, Ontario implemented legislation to limit overlapping multi-jurisdictional class actions among Canadian provinces, allowing the Ontario court to grant remedies that would streamline the overall prosecution of claims being advanced, which could include granting an order staying the class action in Ontario.33

Ontario's class action legislation is similar to (and indeed, modelled on) Rule 23 of the US Federal Rules of Civil Procedure.34 The court considers the proposed class action in light of the three goals of class actions: judicial economy, access to justice and behaviour modification. The importance of the common issues in relation to the claim as a whole is a factor in this analysis.35 If resolution of the common issues would not significantly advance the litigation, and individual trials for each class member would be required, the action will not be certified.36


Price-fixing class actions potentially raise two different jurisdictional issues. The first is whether the court has jurisdiction over the claim. Courts have generally held that if an international price-fixing conspiracy has caused losses in Canada, Canadian courts have jurisdiction.37

Courts in most Canadian provinces will take jurisdiction over matters that have a 'real and substantial connection' with that province. The party asserting that the court should assume jurisdiction has the burden of identifying the connecting factors that link the subject matter of the action to the jurisdiction. Certain connecting factors are considered presumptive: that is, if they exist, the court will have jurisdiction.38

These presumptive factors are:

  1. the defendant is domiciled or resident in the province;
  2. the defendant carries on business in the province;
  3. the tort was committed in the province; and
  4. a contract connected with the dispute was made in the province.

However, these factors are merely presumptive, and do not preclude an action against a foreign defendant that never had any business presence in the jurisdiction if the defendant allegedly participated in a conspiracy that impacted the jurisdiction, a British Columbia court recently confirmed.39

Because of the presumptive factors, and the court's consideration of the impact of the conduct, it is generally difficult for defendants to be successful on a jurisdictional challenge. However, in an April 2015 decision, two defendants successfully had a price-fixing claim dismissed against them for lack of jurisdiction. The judge found insufficient evidence showing a connection to Ontario, including insufficient evidence that the defendants did business in Ontario or were parties to the conspiracy, or that the product at issue would have made its way through the normal channels of trade to Ontario.40

Quebec has codified a similar set of connecting factors that allow its courts to assume jurisdiction.41

With respect to class members, the Court of Appeal for Ontario has held that Ontario courts have extraterritorial jurisdiction over absent foreign class members when:

  1. there is a real and substantial connection between the subject matter of the action and Ontario, and jurisdiction exists over the representative plaintiff and the defendants;
  2. there are common issues between the claims of the representative plaintiff and absent foreign claimants; and
  3. the procedural safeguards of adequacy of representation, adequacy of notice and the right to opt out are provided, thereby serving to enhance the real and substantial connection between absent foreign claimants and Ontario.42

The second jurisdictional issue goes to the criminal offence under the Competition Act that serves as the basis for a claim. The offence of conspiracy under Section 45 is complete as soon as a prohibited agreement is reached. Implementation of the agreement is not one of the elements of the offence; nor are the effects of the agreement on competition. Where a price-fixing conspiracy is entered into outside Canada, it is at least arguable that the offence took place outside Canada, and thus outside of the reach of Canada's criminal law jurisdiction, which is territorial in nature.43 The presence of Section 47 of the Competition Act, which makes it an absolute liability offence for Canadian subsidiaries to implement conspiracies entered into by their foreign parents, reinforces this argument. Against this, Canadian courts now take an expansive approach to criminal jurisdiction.44 The question of whether a price-fixing conspiracy entered into outside Canada by foreign entities is an offence in Canada under Section 45 has yet to be determined.

Parties wishing to contest jurisdiction are required to bring their jurisdiction motions promptly, as their participation in any further steps in the proceeding (such as responding to the certification motion) will constitute attornment.45

Because class actions have a preclusive effect against potential plaintiffs, the question of whether a court validly assumes jurisdiction over the entire plaintiff class also arises. It is well established that a class in, say, Ontario, can include plaintiffs from other Canadian provinces, even on an opt-out basis. Ontario's Class Proceedings Act expressly allows this, and other Canadian provinces will enforce any judgment arising out of the Ontario proceedings. Where a plaintiff class is proposed that includes members from outside Canada, the question becomes more difficult.


i Standing with respect to criminal practices or breach of orders

Canada has an expansive concept of standing in private actions for damages in instances where there is an alleged violation of the criminal provisions of the Competition Act or breach of an order of the Tribunal or other court made under the Act. Section 36 of the Competition Act provides that any person who has suffered loss or damage as a result of such conduct may commence a private action to seek redress.

The Supreme Court of Canada has recently made clear that indirect purchasers have standing to sue and seek damages in price-fixing cases, subject to the caveat that indirect purchasers must be able to prove that they have actually suffered loss or damage as a result of the complained-about conduct.46 A class member cannot recover damages merely based on the fact that there has been a price-fixing conspiracy, and that somewhere down the distribution chain the class member purchased a good that contained the price-fixed component.47 Proof of loss is required for each member of the class in order to recover damages after trial.48 This is typically done by way of expert economic evidence, as discussed below.

Similarly, umbrella purchasers – those class members who purchased goods in a price-fixed market but from a non-conspirator that was able to raise its own prices because of the conspiracy – have a viable cause of action against conspirators, subject to being able to make out on the evidence at trial that the goods they purchased were indeed priced supra-competitively as a result of the conspiracy.49

ii Standing with respect to non-criminal restrictive trade practices

Canada has a very limited scope for the private enforcement of non-criminal restrictive trade practices. Private party prosecution of such trade practices is limited to instances of refusal to deal (Section 75 of the Competition Act), price maintenance (Section 76 of the Competition Act), and exclusive dealing, tied selling and market restriction (collectively, Section 77 of the Competition Act). To commence a private prosecution before the Competition Tribunal, a party must first obtain leave of the Tribunal, which pursuant to Section 103.1 of the Competition Act will only be granted where the Tribunal has reason to believe that the party is directly and substantially affected in its business by the trade practice in question.

Leave to commence a private prosecution under Section 103.1 is rarely sought and even more rarely granted.

The process of discovery

In Canadian class actions, the discovery process occurs after the class action has been certified. The certification motion is procedural in nature, and there is no thorough probing of the merits at the certification hearing and no right to pre-certification discovery.

The discovery process occurs in two stages. The first stage is documentary discovery, wherein parties must disclose and produce all non-privileged relevant documents that are in their power, possession and control. 'Documents' is very broadly defined, and includes all relevant electronic data. As a general principle, the obligation to produce documents is tempered by the principle of proportionality, which is directed by the size and complexity of the case at hand. Because price-fixing class actions are typically factually complex with plaintiffs seeking a large quantum of damages, documentary production is usually extensive.

Recently, in Imperial Oil v. Jacques,50 the Supreme Court held that plaintiffs in a price-fixing class action were permitted to obtain as part of the production process wiretap evidence obtained by the Competition Bureau in the course of the Bureau's criminal price-fixing investigation. This decision will make it easier for plaintiffs to obtain information disclosed to a criminal defendant in the Crown brief in follow-on price-fixing class actions. However, plaintiffs do not have carte blanche to obtain production of the entire investigatory file of the Bureau, and the Bureau has stated that it will oppose such requests.51

A British Columbia court held that information provided to the Bureau by third parties uninvolved in the litigation was protected from disclosure in a civil action by way of public interest privilege.52

Oral discovery follows the production of documents. In some jurisdictions, such as Ontario, a party is limited to having to produce one representative to be discovered, who must take steps to inform him or herself about matters within the collective corporate knowledge in advance of being examined. Even with such preparation, there are generally questions at discovery that go beyond the knowledge of the corporate representative, necessitating the need for the examinee to give undertakings to seek information and documentation from other sources within the corporation. In some instances, members of the class beyond just the representative plaintiff will be subjected to oral discovery, for example in a situation where different groups of class members are differently situated than the representative plaintiff, and the defendants require access to such evidence to properly present a defence.53

Other Canadian jurisdictions, such as Alberta, have a more expansive right of discovery covering multiple corporate representatives, which is more in line with the US deposition process.

Oral discovery of non-parties is typically available only with leave of the court. Members of the Competition Bureau investigatory team are not obligated to attend discoveries in follow-on civil litigation to answer questions about criminal investigations under the Competition Act.54

The process of discovery is similar for matters before the Competition Tribunal. Parties in proceedings before the Tribunal are required to make documentary production and participate in oral discovery.55

Use of experts

The use of experts is commonplace in Canadian competition proceedings, both in class actions in the civil courts and in reviewable matters before the Competition Tribunal. The most common types of experts put forward in competition proceedings are expert economists and industry-specific experts.

In class actions, experts are used at the certification stage, and also at trial. On the certification motion, the plaintiff bears the burden of demonstrating some basis in fact to show that the alleged criminal conduct caused harm down to each purchaser level encompassed by the proposed class.56 This is typically done by way of economic modelling and proposed methodologies by an expert economist.

On the certification motion, the plaintiff's expert does not need to actually quantify the overcharge paid by indirect purchasers: the quantification of the overcharge is done at trial with a full evidentiary record. Rather, on certification the expert must present a methodology that establishes that the overcharge has been passed down through the distribution chain to the indirect purchaser level.57 On the certification motion, the expert's methodology must only offer a realistic prospect of establishing loss on a class-wide basis. At trial, class members are required to prove loss to obtain recovery.58

Defendants on a certification motion have a high hurdle in refuting a plaintiff expert's methodology, and will only succeed if they are able to show that the plaintiff expert's methodology is implausible. The Supreme Court has held that on the certification motion, it is not the role of the certification judge to resolve conflicts between experts, which makes it difficult (although not impossible) for defendants to succeed in an economist-versus-economist battle at certification.59

One strategy employed by defendants in responding to a certification motion is to put forward evidence from an industry expert to demonstrate that, contrary to the theoretical approach of the plaintiff's economic expert, based on how the industry actually works (including the mechanics of the distribution chain) any overcharge would not have been uniformly or consistently passed on through various points of the distribution chain, or would not have made it to the ultimate end purchaser of a price-fixed good. The strategy here (as well as with an economics expert) is to demonstrate that there are complexities in pass-on that the plaintiff expert has not, and indeed cannot, consider or capture such that the class would include those who have suffered no harm.

In proceedings before the Competition Tribunal, complex economic evidence is tendered by both sides geared at demonstrating the effect on competition (or lack thereof) concerning the reviewable practice at issue in a given proceeding. The Tribunal itself is also empowered to appoint independent experts to assist it regarding 'any question of fact or opinion relevant to an issue in a proceeding'.60

Class actions

In Canada, class action legislation has been enacted by all provinces except Prince Edward Island, although not in the territories.61 In 2002, the Federal Court also created specific class proceeding provisions; however, this was not done through independent legislation, but rather through the amendment of the Federal Court Rules.

i Requirements for certification

While there are some differences in the precise language used in the class action legislation enacted in the various jurisdictions, generally speaking a class action will be certified if the following criteria are met:

  1. the pleadings disclose a cause of action;
  2. there is an identifiable class of two or more persons;
  3. the claims of the class members raise common issues;
  4. a class proceeding is the preferable procedure for the resolution of the common issues; and
  5. there is a representative plaintiff who can fairly and adequately represent the interests of the class, and a workable plan for advancing the proceeding.

In Quebec, which is a civil law jurisdiction, there are two primary distinctions: a numerosity requirement, and no specific requirement that the proposed class action meet the preferable procedure test.

ii Notice

Notice to class members is an important component of the class proceeding process. Because individual class members are not active participants in the conduct of the action, notice provides the only real mechanism to inform class members of decisions made by the court in respect of major steps in the litigation. Notice is typically provided through publication in national media, industry magazines, distribution to industry associations, direct mailings to persons involved in the industry and on class counsel websites. The extent and types of notice will vary depending on the nature, scope and value of the claims. While not an exhaustive list, notice is given in the context of certification and settlement, and in respect of the claims process.

Notice of certification is particularly important in jurisdictions that have an opt-in process. In these jurisdictions, class members who fall within the defined class of persons have to take steps to become part of the action. This is distinct from opt-out jurisdictions where, once a class has been certified, any member of the defined class is presumed to be part of the proceeding unless they take steps to opt out of the proceeding.

When one or more defendants in an action settle with the plaintiff, a notice of settlement will be published in advance of the settlement approval hearing to permit people to consider the settlement and allow a class member to object to the settlement. Objectors may make submissions in writing or at the hearing. While objectors may make submissions, they do not gain party status with accompanying rights of appeal. Settlements must be approved by the court, which must satisfy itself that a settlement is fair, reasonable and in the best interests of the class.

iii Settlements in class proceedings

Settlements before trial are the norm in competition class actions. Settlements are negotiated between the parties, often using settlements of related proceedings in the United States as benchmarks for settlement quantum. Where the settlement amount owed to each individual class member is quite small, distribution of the settlement funds may be made cy-pres to organisations such as charities.

Unlike the United States, there is no procedure similar to a multi-district litigation process. The effect of this is that where class actions are commenced in various provinces (often with plaintiff counsel working cooperatively in the different jurisdictions), settlements must be approved in each jurisdiction. There is a growing trend to conduct these hearings via video conference with the different jurisdictions participating at the same time. In these circumstances, each judge sits within his or her own jurisdiction, with all participants linked by video (or telephone) conference. In its 2016 decision in Endean v. British Columbia,62 the Supreme Court ruled that superior court judges can sit outside their home provinces. This decision will facilitate the management of national class actions, including private antitrust class actions.

Calculating damages

Section 36 of the Competition Act provides for the recovery of damages, by individuals or companies, incurred as the result of a violation of the Act's criminal provisions.63 The damage recovery permitted by Section 36 is compensatory in nature only; class members must have suffered actual loss or harm as a result of the alleged breach of the Act by the defendant.64 This means that it is not sufficient for a private defendant to simply point to anticompetitive conduct that did not affect it. It also permits the plaintiff to recover the costs of any investigation into the matter.

Plaintiffs' claims for damages under Section 36 of the Competition Act are often accompanied by claims grounded in tort based on breaches of the Act. These claims permit, in principle, the recovery of punitive damages as well as damages through restitutionary principles. The Supreme Court has confirmed that such equitable and common law claims may be pursued alongside Competition Act damages.65

To date, none of the contested actions based on Section 36 has made it to trial. Consequently, there are no decisions providing judicial guidance on the appropriate methodology for damages calculations or other damages-related issues. Most judicial commentary in respect of damages has been in the context of class certification and settlements.

The most common approach used for damages calculations is based on an analysis of the difference in price between the alleged cartel pricing and a competitive price that would have been in play but for the cartel. That price differential is used to estimate the amount of the 'overcharge'. Typically, expert evidence, including regression analysis (or, in the case of an expert's report at certification, regression modelling), is relied upon to estimate the quantum of overcharge as well as to address pass-through (or pass-on) issues.

Pass-on defences

In 2013, the Supreme Court heard a trilogy66 of cases that addressed, among other things, the availability of indirect purchasers to maintain a cause of gain against alleged cartel members, particularly given that the pass-on defence had earlier been rejected by the Supreme Court.67 Until the trilogy, lower courts had generally avoided dealing with the problems associated with indirect purchaser claims. The Court held that the rejection of the defensive use of pass-on did not entail, as a necessary corollary, the rejection of the offensive use of pass-on. Both direct and indirect purchasers can make a claim and, unlike in the United States, for example, such claims can be joined in one action.

Follow-on litigation

The Competition Act creates a statutory cause of action for anyone who has suffered loss as a result of a criminal breach of the Act.68 Damages under this provision are limited to actual damages suffered, plus costs.

The Competition Act provides that proof of a criminal conviction can be used as proof of the offence in a subsequent private action.69 While a plaintiff can obtain evidence disclosed to a criminal accused as part of a crown brief during the discovery process, a plaintiff will not have access to the Bureau's investigatory file and does not have the ability to summons members of the Bureau for oral discovery.70

When there is no prior criminal conviction, a plaintiff can still bring a civil claim against the defendant, but must prove all elements of the case on a civil standard (i.e., on a balance of probabilities).71 Plaintiffs typically also plead various ancillary common law and equitable causes of action in bringing private actions under the Competition Act. Because these other causes of action are not available in the Federal Court, private actions are almost always commenced in provincial superior courts.

Private actions are commonly structured as a class action under provincial class proceedings statutes. Private actions can be structured as class actions in any of Canada's 14 legal jurisdictions (10 provinces, three territories and the Federal Court), although each jurisdiction has its own particular rules.

Some of the Competition Act's civil provisions, notably refusal to deal, tied selling, exclusive dealing and market restriction, allow for private enforcement by affected firms; however, before commencing an application, the injured party must obtain leave (permission) from the Competition Tribunal. One of the requirements for obtaining leave is a certification by the Commissioner of Competition that the matter is not the subject of an inquiry or application by the Commissioner to the Tribunal.

There is no right of private action under the abuse of dominance, anticompetitive agreements or merger provisions of the Competition Act.


i Solicitor–client privilege

Solicitor–client privilege protects communications between solicitor and client that are made in confidence for the purpose of giving or receiving legal advice. This privilege belongs to the client and is a permanent right; it survives the retainer and even past the client's death. Communications with in-house counsel containing legal advice or for the purpose of obtaining legal advice are subject to solicitor–client privilege so long as the communications are made in the context of performing the function of legal counsel to the company. This privilege does not apply when the communications are made while in-house counsel is acting in some other non-legal capacity.

ii Litigation privilege

Litigation privilege applies to work product and communications that are made specifically in contemplation of existing or anticipated litigation. Litigation privilege also applies to communications with third parties where the dominant purpose of the communication is to assist with existing or anticipated litigation. This privilege, and the protections flowing therefrom, ends with the resolution of the action.

iii Settlement privilege

Settlement privilege attaches to communications between parties made on a without prejudice basis that relate to settlement or were made for the purpose of attempting to resolve a dispute. In these circumstances, communications will be protected from disclosure to the court by settlement privilege, subject to certain exceptions.72

iv Case-by-case privilege: the Wigmore test

Communications or documents that do not fall within one of the class privileges discussed above can be nonetheless subject to privilege if the party claiming privilege can demonstrate that the communication or document should remain confidential based on four criteria, known as the Wigmore test:

  1. the communications must originate in a confidence that they will not be disclosed;
  2. this element of confidentiality must be essential to the full and satisfactory maintenance of the relation between the parties;
  3. the relation must be one that in the opinion of the community ought to be sedulously fostered; and
  4. the injury that would inure to the relation by the disclosure of the communications must be greater than the benefit thereby gained for the correct disposal of litigation.73

The onus is on the party seeking to prevent disclosure to demonstrate on a balance of probabilities that each criterion has been met.

Settlement procedures

Settlements are actively encouraged by Canadian courts, and many jurisdictions have mandatory mediation requirements in their civil procedure rules. Most class actions commenced to date have not proceeded to trial, and are settled before and after class certification. Moreover, due to the multi-jurisdictional nature of class actions in Canada, we are seeing an increased use of global settlement agreements, which serve to resolve the actions in each of the jurisdictions by way of one settlement agreement.

Settlements of class actions require court approval (with some exceptions).74 With respect to class actions, the settlement process usually occurs in two stages: certification as against a party for the purpose of settlement and notice to class members regarding the settlement hearing, and approval of the settlement agreement itself. Objectors, including non-settling defendants and class members, can make submissions at each stage, and can voice their concerns about the fairness or reasonableness of the agreement or to ensure that certain protections are included within the order to appropriately protect their interests.

There is generally close judicial scrutiny of class action settlement agreements in Canada, and Canadian courts have not hesitated to refuse to provide their approval if they deem an agreement to be unfair.75 While most provincial legislation does not specify criteria for approving a settlement, the test at common law is whether the settlement is 'fair, reasonable and in the interests of all those affected by it'.76 Ontario mandates that the court consider certain factors in determining whether to approve a settlement, and these factors largely mirror the common law test.77

In determining whether to approve a class action settlement, the court will consider a number of criteria, including:

  1. the likelihood of recovery or success if the case were litigated;
  2. the amount and nature of discovery or investigation;
  3. the terms and conditions of the settlement;
  4. recommendations of counsel;
  5. future expense and likely duration of litigation;
  6. recommendations of neutral parties or experts;
  7. the number and nature of objections from class members;
  8. the presence of good-faith bargaining; and
  9. the absence of collusion.78


As long as all litigants consent – or at least those who are willing to have their portions of a litigated case determined – parties may submit a matter to a private arbitrator or panel of arbitrators.

Submitting a matter to arbitration would afford litigants the latitude to select the arbitrator or arbitrators, maintain confidentiality, and tailor evidentiary and procedural rules, although not all of these options are mandatory or provided for at law. The key, however, is that the process must be a voluntary one. Most provincial consumer protection statutes forbid terms in consumer contracts that require disputes to be submitted to arbitration.

A note about class actions: a private antitrust claim has never been submitted to or attempted to be submitted to arbitration. Much as would be the case with class settlements, the courts would have to approve any request to submit a matter to arbitration as being in the interests of the class members. Instead of arbitration, lawyers have been engaging mediators in an attempt to resolve class actions during the early stages, such as before a class certification motion or prior to certification, but before further substantive steps are undertaken, such as discovery.

Indemnification and contribution

Generally, rules of court, or the Rules of Civil Procedure in Canadian provinces that govern the administration of justice, specifically permit claims for cross and third-party claims for contribution and indemnity. Limitation statutes sometimes prevent such claims from being advanced after the expiry of the applicable limitation period, such as two years, but parties are usually permitted to extend, or toll, limitation periods by agreement. Tolling a limitation period in Quebec, to the extent that such a notion is permissible under Quebec's Civil Code, is not so straightforward.

In the case of private antitrust cases, plaintiffs' counsel have argued that civil defendants should not be permitted to make claims for contribution and indemnity. While no court has specifically dealt with this issue, and despite the provisions specifically permitting such claims in the various rules of court, the argument for denying contribution and indemnity is premised on the fact that where conduct complained of is covered by the criminal provisions of the Competition Act, and because in the criminal context defendants are not permitted to claim contribution and indemnity among themselves, then the same rule should apply in civil courts. Differing burdens of proof between civil and criminal acts will have to be considered by the courts if this issue is decided, along with the fact that private competition claims also allege various common law torts, such as the tort of civil conspiracy, which obviously does not rise to the level of criminal conduct in and of itself.

Further complicating the issue is that defendants who settle competition class actions usually, as part of their settlement, require and obtain an order from the court barring any future proceedings against them, including any cross-claims or claims for contribution and indemnity. The trade-off that is usually satisfactory to the courts is that the plaintiffs will be precluded from seeking from any non-settling defendants the proportionate share of the settling defendants' liability. If the non-settling defendants are precluded by way of a court order from seeking contribution and indemnity, the logic holds, then they should not be burdened with the liability of the settling defendants.

Future developments and outlook

The Supreme Court's 2019 decision in Godfrey provided significant clarity on many outstanding issues in Canadian price-fixing jurisprudence. In effect, the Supreme Court removed or curtailed many of the arguments typically used by defendants in resisting certification. Godfrey will make it easier to certify price-fixing class actions. In contrast, the Ontario amendments to its class proceedings legislation will impose new challenges on class counsel. Given the relative rarity of contested price-fixing certification decisions, it remains to be seen how the Ontario amendments and the Godfrey decision will interface, both in terms of decided cases and the strategy of litigants.

21 Section 36 is also available to recover damages caused by violations of orders made under the Competition Act by the Competition Tribunal or a court. Indirect purchaser class actions under this branch are unlikely. Section 36 provides in part as follows:

Recovery of damages
36. (1) Any person who has suffered loss or damage as a result of
(a) conduct that is contrary to any provision of Part VI, or
(b) the failure of any person to comply with an order of the Tribunal or another court under this Act, may, in any court of competent jurisdiction, sue for and recover from the person who engaged in the conduct or failed to comply with the order an amount equal to the loss or damage proved to have been suffered by him, together with any additional amount that the court may allow not exceeding the full cost to him of any investigation in connection with the matter and of proceedings under this section

22 F. H. McDougall, [2008] SCC 53 at Paragraph 49.

23 Moreover, rules against collateral attacks on the result of proceedings that are concluded would likely bar any attempt by a person convicted of a criminal offence under the Competition Act to establish that no offence was, in fact, committed.

29 Section 36(3) grants jurisdiction to the Federal Court of Canada to hear Section 36 actions. The superior courts in each province are courts of inherent jurisdiction. They hear virtually all civil and important criminal matters, whether they are local, interprovincial or even international, and whether they involve provincial or federal law. The Federal Court of Canada has only limited statutory jurisdiction, mainly involving federal statutes, income tax, immigration and the like. It does not have jurisdiction over common law claims between private parties. The only significant private law jurisdiction of the Federal Court is over intellectual property, admiralty law and actions under Section 36 of the Competition Act. Because the Federal Court does not have jurisdiction over the common law claims typically associated with Section 36 private actions, such claims are only rarely advanced in the Federal Court.

30 SO 1992, c 6.

31 The following provinces have class proceedings legislation similar to Ontario's: British Columbia (Class Proceedings Act, RSBC 1996, c 50), Alberta (Class Proceedings Act, SA 2003, c C-16.5), Saskatchewan (Class Actions Act, SS 2001, c C-12.01), Manitoba (Class Proceedings Act, CCSM c C130), Quebec (Code of Civil Procedure, RSQ, c C-25, Book IX), New Brunswick (Class Proceedings Act, RSNB 2011, c 125), Nova Scotia (Class Proceedings Act, SNS 2007, c 28), and Newfoundland and Labrador (Class Actions Act, SNL 2001, c C-18). The Federal Court Rules allow class actions within the court's limited jurisdiction. In Western Canadian Shopping Centres v. Bennett Jones Verchere, [2001] 2 S.C.R. 534, the Supreme Court ruled that a class action could be brought even in the absence of class action legislation. Although Quebec was the first province to enact class action legislation, in 1978, its legislation limits the plaintiff classes to individuals and small corporations or associations (fewer than 50 employees).

32 Ontario had been the jurisdiction of choice for national class actions because it has an opt-out regime for national classes, whereas British Columbia required out-of-province members to specifically opt in. British Columbia has a 'no costs' regime, and may become the forum of choice for the plaintiff class action bar, given the procedural change. Alberta, Saskatchewan and Newfoundland and Labrador have adopted opt-in regimes.

33 Class Proceedings Act, 1992, SO 1992, c 6, Section 5(8).

34 Class Proceedings Act, 1992, Section 5 contains the test for certification. It reads in part as follows:

5(1) The court shall, subject to subsection (6) and to section 5.1, certify a class proceeding on a motion under section 2, 3 or 4 if,
  • (a) the pleadings or the notice of application discloses a cause of action;
  • (b) there is an identifiable class of two or more persons that would be represented by the representative plaintiff or defendant;
  • (c) the claims or defences of the class members raise common issues;
  • (d) a class proceeding would be the preferable procedure for the resolution of the common issues; and
  • (e) there is a representative plaintiff or defendant who,
  • (i) would fairly and adequately represent the interests of the class,
  • (ii) has produced a plan for the proceeding that sets out a workable method of advancing the proceeding on behalf of the class and of notifying class members of the proceeding, and
  • (iii) does not have, on the common issues for the class, an interest in conflict with the interests of other class members.
(1.1) In the case of a motion under section 2, a class proceeding is the preferable procedure for the resolution of common issues under clause (1) (d) only if, at a minimum,
  • (a) it is superior to all reasonably available means of determining the entitlement of the class members to relief or addressing the impugned conduct of the defendant, including, as applicable, a quasi-judicial or administrative proceeding, the case management of individual claims in a civil proceeding, or any remedial scheme or program outside of a proceeding;and
  • (b) the questions of fact or law common to the class members predominate over any questions affecting only individual class members.

The test in Manitoba (Section 4), Alberta (Section 5), Saskatchewan (Section 6) and Newfoundland and Labrador (Section 5) is almost identical to Section 5 of the Class Proceedings Act, except that these four statutes add 'whether or not the common issue predominates over issues affecting only individual prospective class members' (or similar) after the equivalent of Section 5(1)(c) of the Class Proceedings Act. The impact of this additional language has yet to be considered judicially, but it is unlikely to have much effect on the test. The British Columbia Class Proceedings Act expressly makes whether the common issues predominate over individual issues a factor in determining whether a class proceeding would be preferable (Section 4(2)(a)). The test in Quebec has the lowest threshold of all: there is no preferable procedure or predominance requirement; it is enough that there are common issues: Code of Civil Procedure, Article 1003(a). In one case, Quebec certified a case rejected by Ontario: contrast MacLeod v. Viacom Entertainment Canada Inc (2003), 28 CPC (5th) 160 (SCJ) with Yadid v. Blockbuster Canada Co [2003] JQ No. 2278 (SC).

Anglo American PLC, 2012 BCCA 257; but see Bouchard v. Ventes de véhicules Mitsubishi du Canada Inc, 2008 QCCS 6033, where the Quebec Superior Court held that an overcharge suffered in Quebec as a result of price-fixing is a pure economic loss that is not damage suffered in Quebec for purposes of Article 3148(3) Quebec Civil Code. In addition, in Shah v. LG Chem, Ltd, 2015 ONSC 2628, the fact that damage was suffered in Ontario was insufficient to establish jurisdiction where the plaintiffs failed to show a 'good arguable case' that the defendant was a party to that conspiracy.

73 Slavutych v. Baker [1976] 1 S.C.R. 254.

74 In Ontario and Quebec, prior court approval, even prior to certification, is required for a proposed class action to be settled or discontinued. The same is true for actions commenced in Federal Court. In the other statutory jurisdictions, court approval is required only after certification has been granted.

75 For example, the Ontario Superior Court recently refused to approve a settlement agreement between Quiznos franchisees, the defendant franchisers and food supplier Good Food Service Inc, finding that the scope of the release was too broad given the nominal amount of damages.
