Canadian Competition Law Framework

Canadian competition law is federal. The primary statute is the Competition Act (RSC 1985, c C-34), administered by the Competition Bureau (an independent law enforcement agency) and enforced before the Competition Tribunal (a specialized adjudicative body) and the Federal Court. The 2022 and 2024 amendments (Bill C-19 and Bill C-56) significantly strengthened the Competition Act — expanding abuse of dominance remedies, adding a drip pricing prohibition, and enabling structural merger remedies.

Ontario lawyers encounter competition law most often in: M&A transactions (merger notification); commercial agreements (distribution, franchise, licensing — ensuring no anti-competitive provisions); marketing and advertising review (deceptive practices); and regulatory matters where clients are under Bureau investigation.

2024 amendment note: Bill C-56 (Affordable Housing and Groceries Act, in force December 2023) amended the Competition Act to: (1) allow the Tribunal to order dissolution in abuse of dominance cases; (2) expand the market studies power; and (3) remove the efficiencies defence in merger cases (eliminating the ability to justify anti-competitive mergers based on cost efficiencies).

Merger Review Process (6 Stages)

1

1. Pre-Merger Assessment

Determine whether transaction meets notification thresholds; assess competitive overlap between parties; consider whether Bureau pre-notification consultation is warranted for complex transactions

2

2. Filing Notification

Submit prescribed information to Competition Bureau within prescribed timelines; both acquirer and target must file where threshold met; filing fee payable (currently $74,680 for standard notification)

3

3. Initial Waiting Period (30 days)

Bureau has 30 days to review from filing; transaction cannot close during waiting period; Bureau may request supplementary information (SIR), which triggers a second 30-day period after SIR compliance

4

4. Bureau Review

Bureau assesses competitive effects in relevant markets; defines product and geographic markets; assesses market shares, barriers to entry, competitive constraints, and efficiencies; contacts customers, competitors, and suppliers

5

5. Resolution

Outcomes: (a) No-action letter (Bureau will not challenge); (b) Consent agreement — parties accept conditions (divestiture, behavioural remedies) to resolve concerns; (c) Application to Competition Tribunal to block transaction

6

6. Tribunal Proceeding (if required)

Bureau applies to Tribunal under s.92 to challenge transaction; full evidentiary hearing; Tribunal may order dissolution, divestiture, or that merger not proceed; parties may argue efficiencies offset competitive harm (s.96)

Advance Ruling Certificate (ARC)

An ARC is a binding commitment by the Commissioner not to challenge a specific transaction for 1 year. ARC applications can be filed before or alongside a notification. Where the Commissioner will not issue an ARC but has no immediate concerns, a "no-action letter" may be issued (non-binding). ARCs provide commercial certainty in complex transactions where competition concerns are unclear.

Competitor Collaborations: Joint Ventures and Agreements

Not all competitor collaborations are anti-competitive. The Competition Act distinguishes between criminal conspiracies (s.45 — per se illegal) and strategic alliances or joint ventures that may be reviewable under s.90.1 (civil collaboration provisions) or the merger provisions.

Criminal Per Se: s.45 Conspiracies

  • Price-fixing (agreeing to fix, raise, maintain, or stabilize prices)
  • Market allocation (dividing territories, customers, or products)
  • Output restriction (agreeing to limit or control production)
  • No defences based on reasonableness or efficiency
  • Ancillary restraints defence: restraint must be directly related to and reasonably necessary for the principal transaction/agreement between the parties

Civil Reviewable: s.90.1 Collaborations

  • Agreements between competitors that prevent or lessen competition substantially
  • Applies to agreements that do not fall under criminal conspiracy provisions
  • Tribunal may make orders to modify, prohibit, or terminate the agreement
  • Efficiency gains may be considered as justification
  • Joint ventures, R&D collaborations, purchasing groups may be reviewable under s.90.1

Deceptive Marketing Practices

The Competition Act prohibits both criminal (s.52 — knowing and reckless) and civil reviewable (s.74.01) deceptive marketing practices. Key Ontario advertising matters:

  • Drip pricing (s.74.01(1.1)): Advertising a price that does not include all mandatory fees or charges; Competition Bureau has issued enforcement guidance and has challenged airlines, event ticketing, and online retailers for drip pricing
  • Performance claims: Claims about performance, efficacy, or length of life must be based on adequate and proper testing before making the representation
  • Ordinary selling price: Representing a price as a regular, ordinary, or usual price must reflect what the product was sold at for a substantial volume of recent sales
  • Fake reviews (s.74.011, since 2024): Purchasing, creating, or using fake online reviews or fake social media engagement is now a reviewable practice under Bill C-56 amendments
  • Dark patterns (s.74.011, since 2024): Online representations designed to obscure, impede, or prevent consumers from exercising rights — including confusing unsubscribe flows and forced continuity clauses — are now deceptive marketing practices

Frequently Asked Questions

When is a merger notifiable under the Competition Act?

A transaction is notifiable when both the size-of-parties threshold ($400 million combined Canadian revenues/assets) and the size-of-transaction threshold ($93 million target Canadian revenues/assets, indexed annually) are met. Notifiable transactions cannot close until the 30-day waiting period expires or the Commissioner issues an ARC or no-action letter.

What is abuse of dominance under the Competition Act?

Under s.79 of the Competition Act, abuse of dominance requires: (1) substantial or complete control of a class of business; (2) a practice of anti-competitive acts; and (3) the practice has had or is likely to have the effect of preventing or lessening competition substantially. Since 2022, the Tribunal can impose administrative monetary penalties up to $35 million for corporate respondents.

What are the penalties for price-fixing in Canada?

Price-fixing conspiracies under s.45 are criminal per se offences since 2010. Penalties include: individual: up to 14 years imprisonment and/or a fine; corporation: up to $25 million per count. The Competition Bureau operates an Immunity Program allowing the first co-conspirator to self-report and cooperate to receive immunity from prosecution.

What is the drip pricing prohibition under the Competition Act?

Amendments effective June 2022 added an express prohibition on drip pricing under s.74.01(1.1) — advertising a price for a product that does not include all mandatory fees or charges. Civil AMPs up to $10 million for first violations, $15 million for subsequent violations, or 3% of annual worldwide revenues. The Bureau has challenged airlines, event ticketing platforms, and online retailers.
