The Competition Act (Canada)

Historical Evolution

The Competition Act, RSC 1985, c C-34, is Canada’s federal antitrust and consumer protection statute. Its origins lie in An Act for the Prevention and Suppression of Combinations formed in restraint of Trade, SC 1889, c 41 — Canada’s first competition law, enacted a year before the US Sherman Act. This early legislation criminalized conspiracy in restraint of trade but proved ineffective due to its requirement to prove mens rea.

The Combines Investigation Act, SC 1910, c 9, replaced the 1889 statute and established an investigative model using a registrar and a board of inquiry. The legislation was substantially revised in 1952, 1960, and 1975. The 1975 amendments introduced reviewable matters — civil rather than criminal — addressing mergers and abuse of dominant position. The modern Competition Act was enacted in 1986 (Bill C-91), replacing the Combines Investigation Act with a bifurcated regime that retained criminal offences for hard-core cartel conduct and introduced a civil review regime for most other anti-competitive conduct.

The Act underwent its most significant reforms in 2022 and 2024. Bill C-19 (Budget Implementation Act, 2022) and Bill C-56 (2023) amended the Act to expand the Competition Tribunal’s remedial powers, introduce an efficiencies defence narrowing (merger-specific efficiencies no longer shield anti-competitive mergers if competition is substantially lessened), increase penalties, and broaden private access. Bill C-59 (2024) further amended the Act to address greenwashing (s. 74.01), employee wage-fixing and no-poach agreements (codified as criminal per se under s. 45), and interim relief provisions.

Institutional Framework

Competition Bureau is the independent law enforcement agency headed by the Commissioner of Competition, appointed under s. 7. The Bureau investigates potential violations under both criminal and civil provisions, conducts market studies, and promotes compliance. It may seek remedies through the Competition Tribunal (for civil matters) or the Superior Court (criminal prosecutions, at the request of the Public Prosecution Service of Canada). The Bureau’s powers include formal examinations (s. 11), search warrants (s. 15), and wiretap authority for criminal investigations. The Bureau has issued numerous Competition Bureau guidelines — notably the Intellectual Property Enforcement Guidelines (2022), the Merger Enforcement Guidelines (2021), and the Wage-Fixing and No-Poach Agreements Enforcement Guidelines (2023) — which, while not legally binding, structure prosecutorial discretion and inform compliance.

The Competition Tribunal is a specialized quasi-judicial body established under the Competition Tribunal Act, RSC 1985, c 19 (2nd Supp). It consists of Federal Court judges and lay members with economics or business expertise. The Tribunal adjudicates civil reviewable matters, including mergers, abuse of dominance, and deceptive marketing. Its remedial powers include dissolution orders, prohibition orders, injunctions, and (post-2023) administrative monetary penalties (AMPs) of up to the greater of CA$10 million (for a first order, or CA$15 million for subsequent orders) per occurrence for individuals, and CA$25 million (CA$35 million for subsequent orders) or three times the gross gain for corporations under s. 74.1.

Criminal Offences

Conspiracy (s. 45) is the Act’s core criminal prohibition. It makes it an indictable offence for competitors to conspire, agree, or arrange to fix prices, allocate markets, or restrict output. Section 45 is a per se offence — no proof of anti-competitive effects is required, and no efficiencies defence is available (R v Nova Scotia Pharmaceutical Society, [1992] 2 SCR 606, the “PANS” case). The mens rea standard is subjective intent (R v Gage, 2015 ONCA 350; R v Paterson, 2016 ONCA 758). Penalties include imprisonment for up to 14 years and fines at the discretion of the court (with no statutory maximum for indictable matters). Bid-rigging (s. 47) is a separate criminal offence prohibiting arrangements among bidders that reduce competition in procurement. Unlike s. 45, bid-rigging applies to both former and prospective competitors. The immunity and leniency programs administered by the Bureau provide full immunity to the first qualifying applicant (s. 45.1) and leniency to subsequent cooperators.

Wage-fixing and no-poach agreements were criminalized effective June 2024 by Bill C-59. Section 45 now explicitly extends to agreements between employers (not just product-market competitors) to fix wages, terms of employment, or not solicit/hire each other’s employees. This amendment resolved prior uncertainty following R v JDS Uniphase (2020, Ontario SCJ) and aligns Canada with US DOJ enforcement policy.

Civil Reviewable Matters

Abuse of dominance (s. 79) prohibits a dominant firm (or firms) from engaging in anti-competitive acts with the purpose, effect, or likely effect of substantially lessening or preventing competition in a market. The three-part test requires: (1) substantial or complete control of a class of business; (2) anti-competitive acts; and (3) a substantial lessening or prevention of competition. Bill C-56 (2023) removed the requirement to prove “intent” to engage in anti-competitive acts and broadened the definition of anti-competitive acts. The Tribunal may now issue orders including structural remedies (divestiture of assets or shares) and AMPs of up to CA$25 million (or CA$35 million for subsequent orders), or three times the value of the benefit derived.

Mergers (s. 92) are subject to pre-notification requirements (s. 114, thresholds indexed annually — in 2024, CA$99 million for transactions involving parties and CA$440 million for the target) and substantive review. The test is whether the merger prevents or substantially lessens competition (the “SLC” test). The Tribunal may order dissolution, divestiture, or other remedies. The efficiencies defence (former s. 96, repealed in 2023) no longer preserves otherwise anti-competitive mergers on efficiency grounds; the Tribunal must consider efficiency as a factor but cannot override a finding of SLC.

Deceptive Marketing and Consumer Protection

Part VII.1 (ss. 74.01–74.18) civilly prohibits false or misleading representations (s. 74.01), performance claims without adequate testing (s. 74.02), and deceptive telemarketing (s. 74.07). Bill C-59 (2024) added greenwashing provisions under s. 74.01, requiring that environmental benefit claims be substantiated by adequate and proper testing in accordance with internationally recognized methodologies. Ordinary civil claims for deceptive marketing are brought by the Commissioner before the Tribunal; the private right of action for damages under s. 36 extends to persons who have suffered loss or damage as a result of conduct contrary to Part VI (criminal) or Part VIII (reviewable matters), though s. 103.1 now provides a broader private access mechanism.

Private Access

Section 103.1, significantly expanded in 2022, allows private parties to apply to the Tribunal for leave to make an application in respect of abuse of dominance (s. 79), refusal to deal (s. 75), price maintenance (s. 76), exclusive dealing (s. 77), tied selling (s. 77), and market restriction (s. 77). The leave threshold requires the applicant to demonstrate that they are directly and substantially affected in their business. The 2022 amendments removed the requirement that the Commissioner not be dealing with the matter, making private applications more available. Successful private applicants may obtain Tribunal orders but not damages; damages are pursued separately under s. 36.

Digital Economy Provisions

The 2022–2024 amendments introduced provisions targeting digital platform conduct. The Tribunal now has jurisdiction to make orders against anti-competitive conduct by dominant digital platforms without a separate “market” definition analysis (s. 78, as amended). The digital platform regulation framework under ss. 90.1–90.8, enacted in 2023, empowers the Governor in Council to make regulations requiring digital platforms to provide interoperability and data portability, though the scope of regulations remains under development. These provisions were influenced by similar reforms in the EU Digital Markets Act, Australia’s News Media Bargaining Code, and the UK’s Digital Markets Unit framework.

Relationship with Provincial Law and Private International Enforcement

The Act operates alongside provincial competition law, such as Quebec’s consumer protection legislation. The federal Act has paramountcy over provincial laws that conflict, though provincial laws of general application (e.g., class actions based on anti-competitive behaviour) continue to apply. Private litigants frequently bring class actions under s. 36 of the Act or under provincial tort law (civil conspiracy) for competition law violations. International enforcement cooperation is governed by bilateral mutual legal assistance treaties and Canada’s participation in the International Competition Network (ICN) and the OECD Competition Committee, though the Federal Court has held in Mitsubishi Heavy Industries that foreign proceedings do not preclude Canadian proceedings where a real and substantial connection exists.
