Canada: Private Antitrust Litigation


Two different venues provide opportunity for private antitrust litigation in Canada. Most commonly used is the civil court system for the pursuit of damages following criminal anti-competitive behaviour - usually pursued by means of class actions. Less common are administrative proceedings before the Canadian Competition Tribunal, which are available to private parties under certain circumstances. This article will describe recent activity in both forums with a focus on civil litigation as it is currently characterised by two important legal issues: who is properly situated as a plaintiff in Canadian competition class actions; and the navigation of multiple and overlapping parallel class actions. It will include a case study of competition class actions in Quebec in recognition of the significant differences between Quebec and the rest of Canada’s class action procedures.

Civil antitrust litigation in Canada

Section 36 of Canada’s Competition Act (the Act) allows private parties to bring an action for losses suffered as a result of conduct that is contrary to the criminal offences in part VI of the Act.1 Actionable criminal offences under section 36 include conspiracy, bid rigging, misleading advertising, deceptive telemarketing and pyramid schemes.2 A prior conviction for those criminal offences is, in the absence of evidence to the contrary, proof that the person engaged in the conduct and any evidence given in the criminal proceedings as to the effect of those acts is available for civil litigants to use.3 In practice, most criminal convictions result from negotiations rather than a trial, meaning the agreed statement of facts will be an important piece of evidence in subsequent civil proceedings. In the absence of a conviction, the usual ‘balance of probabilities’ civil standard of proof applies. Only losses actually suffered, as well as the cost of the resulting investigation and proceedings, may be claimed. Neither punitive nor treble damages are available for actions brought under section 36. The limitation period for proceedings brought under section 36 is two years after the criminal conduct occurred or the criminal proceedings related to that conduct were disposed of, whichever is later.4

Plaintiffs often also frame these actions in common law conspiracy, unlawful interference with economic interests, or similar economic torts. These claims in tort are not limited by the Act and may, as a result, give rise to punitive damages, differing limitation periods, interlocutory injunctions and equitable disgorgements.

In practice, many private antitrust actions in Canada arise out of international conspiracies that are initially investigated, prosecuted and litigated in other countries, particularly the US. As long as the conspiracy has a ‘real and substantial connection’ to Canada, in that the conspiracy, even if formed elsewhere, caused losses that were sustained in Canada, Canadian courts will have jurisdiction over related civil actions.5 Canadian plaintiffs typically attempt to benefit from prior or parallel actions in other countries, particularly from the evidence presented at such actions.

Some of the most recent developments in Canadian antitrust class actions include that the plaintiffs in the Air Cargo class action6 reached settlements with Société Air France, KLM and LAN Airlines, bringing the number of settled defendants in that proceeding to eight. The Air France/KLM and LAN settlements are subject to court approval and are set to be heard in the Summer of 2012. In March 2012, a class action alleging price fixing in retail gas in certain Ontario markets was filed against Pioneer Energy LP, Canadian Tire Corporation and Mr. Gas Limited following the guilty pleas entered by all three of the defendants as part of an investigation conducted by the Competition Bureau.

Requirements for class actions

Civil antitrust litigation in Canada largely proceeds by means of class actions. With the exception of Quebec, class actions filed in any province in Canada must generally satisfy the following five criteria to be granted certification (criteria usually set out in provincial legislation):

  • the pleadings disclose a cause of action;
  • there is an identifiable class of two or more persons;
  • the claims of the class members raise common issues;
  • a class proceeding would be the preferable procedure for the resolution of the common issues; and
  • there is a representative who would fairly and adequately represent the interests of the class, has produced a workable plan for advancing the proceeding and notifying class members, and does not have, on the common issues for the class, an interest in conflict with the interests of other class members.7

Although the criteria are to be construed generously in light of the three goals of class actions - judicial economy, access to justice and behaviour modification - plaintiffs do need to show some basis for each criterion.8 Extensive evidence is now commonplace at the certification stage, including economic expert reports. Notwithstanding the large evidentiary records, courts have shown an increased propensity to certify actions. Whereas a decade ago the inability to demonstrate a common basis for tracing the alleged overcharge to the various class members may have been a sufficient obstacle to certification,9 more recent judgments have simply looked for a credible or plausible methodology to trace damages as amongst class members in order to certify an action for trial.10

Note that a different standard is applied for certification applications presented solely for the purpose of approving a proposed settlement because the courts are focused on whether the settlement is fair to the class. Such certification for settlement purposes is typically expressly done with no prejudicial effect on the non-settling defendants.

Two issues are currently at the forefront of antitrust class actions in Canada. The first issue is whether indirect purchasers are proper members of a plaintiff class. The second issue is the developing response to Canada’s lack of a procedure analogous to the US’s multidistrict litigation system. Both will be described below.

Indirect purchaser claims

Canadian courts have been inconsistent in their treatment of indirect purchaser claims. The Ontario Court of Appeal in Chadha v Bayer refused certification for an indirect purchaser case due to insufficient evidence that there was a common basis to the plaintiffs’ loss and that it was the defendants’ actions that caused the indirect purchasers’ loss.11 However, the Court in Chadha did not go as far as the US court in Illinois Brick12 by holding that no indirect purchaser claim would be possible and indeed, many subsequent claims have been brought in Canada comprising classes of direct and indirect purchasers. The BC Court of Appeal then certified an indirect purchaser class in Pro-Sys Consultants Inc v Infineon Technologies AG,13 holding that the class need only demonstrate an aggregate liability rather than liability to each individual class member. The Ontario Superior Court similarly certified indirect purchaser claims, including one against the alleged Hydrogen Peroxide cartel in a judgment which held that losses need only be proven at the class level.14

In 2011, however, the BC Court of Appeal, in a split decision, rejected two indirect purchaser claims in the companion cases of Pro-Sys Consultants Ltd v Microsoft Corporation (Microsoft) and Sun-Rype Products Ltd v Archer Daniels Midland Company (Sun-Rype).15 The Court found that, because a previous Supreme Court decision had rejected the passing-on defence against direct purchaser claims, indirect purchaser claims should not be permitted as it would give rise to problems such as the possibility of double recovery.16 In reviewing previous indirect purchaser claims that were certified, the Court noted that the certification was either pursuant to a settlement, not opposed, or granted because it was not clear the action would fail and thus the issue would be better ‘addressed on a trial with the benefit of a full evidentiary record.’17

Shortly thereafter, the Quebec Court of Appeal came to the opposite conclusion in a decision cited as Option Consommateurs v Infineon Technologies (Option Consommateurs),18 which arose out of the alleged DRAM cartel.19 Initially at trial, certification of this proceeding was denied because the judge ruled, among other things, that the facts alleged did not support the conclusion that the indirect purchasers suffered harm. The Quebec Court of Appeal disagreed in a judgment that approved of the dissenting judgment in the BC indirect purchaser actions. With respect to the indirect purchaser issues, the Court noted that there was no danger of double recovery because the case would deal with the entirety of the loss to both direct and indirect purchasers.20 Any problems regarding how to divide the damages between direct and indirect purchasers should be dealt with at trial and should not result in the action failing at the certification stage. Similarly, potential future conflicts between class members should not be fatal to the action; at this stage, all class members share the goal of obtaining the greatest amount of damages possible.

The Supreme Court of Canada has granted leave to appeal Microsoft and Sun-Rype, along with the Quebec case that reached the opposite conclusion. The Supreme Court is tentatively scheduled to hear these appeals in October 2012, and on that basis a decision is expected in late Spring 2013.21 Until that time, the issue as to who is properly situated to be a class member in antitrust litigation is in a state of uncertainty and confusion. Certain current class actions proceedings are being stayed (some by Court Order and some by agreement between the parties) until a ruling of the Supreme Court is released to avoid wasted time and costs spent framing a case the Supreme Court later rules not-permissible.

Class actions in Quebec

The indirect purchaser issue is not the only issue in class actions on which the province of Quebec has taken a different approach. Differences in that jurisdiction are important to note given their potential impact on litigation precedents nationally and, as discussed further below, Canada’s ability to organise and consolidate multiple parallel proceedings.

Class action proceedings in Quebec are governed by a distinct set of rules found in the Code of Civil Procedure. Individual or non-profit organisation plaintiffs have the option of receiving funding from the Fonds d’aide aux recours collectifs.22 Only individuals, non-profit organisations and private-interest entities with fewer than 50 employees can be plaintiffs in a class action. In order to be certified,23 proposed class proceedings must meet criteria similar to those for class certification in the rest of Canada.24 However, unlike the common law provinces, Quebec judges do not have broad discretionary power. Instead, they have more limited discretion to determine whether each of the criteria are fulfilled;25 and if those criteria are fulfilled, judges must certify the action. Plaintiffs need only demonstrate a prima facie case, and any doubt must be resolved in favour of the plaintiffs.26 Judges may play a more active role, with the ability but not the obligation to redefine the class so that it can be certified.27 Written arguments are not permitted at the certification stage, and parties must apply for leave to conduct examinations or file evidence.28 Judgments granting certification cannot be appealed by defendants.29

Recent Quebec antitrust class actions reveal some of the above-noted differences in practice. Harmegnies v Toyota Canada, a series of judgments that ended in 2008 at the Quebec Court of Appeal, was an attempt to certify a class action alleging Toyota’s ‘Access Toyota’ programme maintained the resale prices of new Toyota vehicles. The Quebec Court of Appeal denied certification because, inter alia, the liability of Toyota and the dealers could not be established without individualised analysis of each class member. More to the point here, the Quebec Court of Appeal noted that, although prior cases in other provinces and the US were valuable, they should be used with care in Quebec due to differences in the law, particularly at the certification stage.

One year later the Jacques v Petro-Canada action was certified despite significant differences between the proposed class members.30 The action was against gas companies in four geographic areas, alleging a conspiracy to fix gas prices. The judgment acknowledged that wide price fluctuations meant that not all of the proposed class members actually suffered damages, and that it would be difficult to quantify the damages suffered by each individual. Nevertheless, it concluded that there was, in contrast with Toyota, a collective injury, and any difficulty regarding how to quantify damages does not negate its existence or its calculation in the aggregate. The trial judge also used her discretion to redefine the class as the original description was insufficiently precise to be certified.

In Option Consommateurs, the Court commented on the fact that parties cannot, in the absence of leave, adduce evidence at the certification stage. In the words of the Court, ‘the presentation of expert evidence is not the norm at the [certification] stage in Quebec [...] and, where rules applicable elsewhere might require a sophisticated methodology of proof of loss to be advanced before certification of a class action, the absence of such a methodology is not fatal here.’31 In a demonstration of the rule regarding evidence at certification, the Court also upheld the trial judge’s refusal to postpone the proceedings in order to allow the defendant to adduce evidence, noting that the trial judge had previously refused permission to the plaintiffs to adduce evidence.32

As mentioned above, the Supreme Court has granted leave to appeal to Option Consommateurs, Pro-Sys and Sun-Rype, which all deal with indirect purchaser claims but which reached different conclusions. The outcome of that appeal should settle this issue and provide reliable guidance for future actions. No such guidance seems imminent, however, for the issue of multiple parallel class actions.

Multiple parallel class actions

It is typical for various plaintiffs’ counsel to file parallel proceedings in a number of Canadian provincial jurisdictions. Unlike the US, which has a procedure to consolidate multiple parallel class actions, there is no equivalent procedure in Canada. There is a growing recognition that national classes, or some form of inter-provincial cooperation, is desirable. The current practice of having multiple parallel proceedings gives rise to inefficiencies and inconsistent outcomes. Although the informal practice is to designate proceedings in one province as the lead case and stay other proceedings, such practices are ad hoc and are not legally binding for defendants. Again, at times, Quebec proves to be a differing factor. In certain cases, Quebec courts have recognised similar proceedings in other provinces,33 but have also held that separate Quebec class actions are not necessarily barred by national class action settlements.34 Where overlapping class actions cannot be informally coordinated between counsel, motions may be required which can become costly.

In response to the legal lacuna regarding national classes, the Canadian Bar Association (CBA) launched a National Task Force on Class Actions in 2010. The CBA approved the resulting Canadian Judicial Protocol for the Management of Multi-Jurisdictional Class Actions as best practice, and endorsed two of the American Bar Association’s protocols regarding cross-border and multijurisdictional class actions. The Canadian Judicial Protocol aims to facilitate communications regarding developments and settlements by creating a Notification List of all counsel involved in all related actions. The CBA has also created a National Class Action Database to provide class action information and documents, including pleadings, to the public.35 Despite a growing trend to accept the practical advantages of the Judicial Protocol, it remains optional.

Private administrative proceedings

In addition to criminal offences, the Competition Act prohibits certain trade practices such as abuse of dominance, exclusive dealing, tied selling and refusal to deal. These practices are reviewable by the Competition Tribunal. Most of the proceedings that come before the Tribunal are brought by the commissioner of competition. Indeed for certain provisions - such as abuse of dominance - the commissioner is the only party entitled to initiate a proceeding.36 However, recent amendments granted the right to private individuals to bring applications before the Tribunal, subject to obtaining leave.37 This right is available for conduct constituting price maintenance, refusal to deal and exclusive dealing, tied selling and market restrictions. Leave to bring an application under any of these provisions will not be granted if the matter is already being handled by the commissioner or was previously settled by the commissioner. The applicant must also demonstrate that he is ‘directly and substantially affected’ by the alleged conduct. Although the standard for this requirement is lower than the balance of probabilities, few private litigants have been able to demonstrate that they were substantially affected by the conduct. Since the first application for leave was brought and denied in 2002, most leave applications have been denied. One that was granted is discussed below. Remedies for actions brought before the Tribunal by private parties are limited to behaviour modification orders; damages are not available.

In terms of applications brought by private parties, one piece of ongoing litigation before the Tribunal is Used Car Dealers Association of Ontario v Insurance Bureau of Canada. The Used Car Dealers Association (UCDA) is a not-for-profit organisation that provides a number of services to its members (motor vehicle dealers), such as Autocheck, which provides dealers with information about the accident history of vehicles they sell. The Tribunal gave leave to an application by the UCDA claiming that the Insurance Bureau of Canada’s (IBC) refusal to provide them with claims data regarding the accident history of cars constituted a refusal to deal.38 According to the application, the IBC is the sole source of comprehensive claims data. The UCDA sought interim relief, which resulted in an interim supply order on consent. In March 2012, the UCDA won a motion when the IBC unsuccessfully sought permission to rescind the negotiated interim supply order granting UCDA access to the data during the proceedings. Examinations for discovery are currently scheduled for September 2012, while the hearing is scheduled for April 2013.

An example of an action that failed on the merits is Nadeau Poultry Farm Ltd v Groupe Westco Inc, another refusal to deal claim. Nadeau accused Westco, a competitor, of refusing to sell them live chickens to be processed at their plant, contrary to the Act. Nadeau was granted leave and interim relief, namely that Westco was to supply Nadeau with live chickens on usual trade terms. However, the Competition Tribunal ruled against Nadeau on the merits, finding that Nadeau’s inability to access adequate supplies of live chickens was not the result of insufficient competition, and that the refusal to deal was not likely to have an adverse effect on competition in the market. The decision was upheld by the Federal Court of Appeal, and costs were awarded to Westco.39


Although there are two venues for private antitrust litigation, most activity in Canada is found in the class actions brought before the regular courts, under the Act and through actions in tort. The most pressing issues remain indirect purchaser claims and multiple parallel class actions, though the former issue will likely be settled by the Supreme Court within the next year. Differences between provinces, changing caselaw and trends regarding cross-border issues will remain important and require practitioners to keep a sharp eye on this area of the law.
