A Quebec judge authorized a class-action lawsuit against Tim Hortons, Starbucks, and Second Cup on June 16, 2026, over non-dairy milk surcharges that plaintiffs allege constituted unfair pricing — the latest in a cluster of legal challenges now surrounding the Canadian coffee chain in that province.

The non-dairy milk case centres on a familiar consumer grievance: chains charging a premium for oat milk or other plant-based alternatives that exceeds their actual cost differential. In Tim Hortons' case, internal pricing data surfaced in a separate proceeding revealed the company charged customers 50 cents for a non-dairy swap while its cost in eastern Quebec ran to 28 cents — a margin that forms part of the plaintiffs' unfair-pricing argument. Authorization by a Quebec Superior Court judge does not constitute a finding of liability; it means the court is satisfied that the case raises questions of law or fact common to the proposed class that warrant a collective proceeding.

Franchisees vs. Head Office

The non-dairy suit is not the only active front. Fifteen Quebec franchisees filed suit against Tim Hortons in 2024, claiming corporate decisions — over pricing, supply, and operational mandates — had eroded their profitability to the tune of CA$27 million. In June 2026, Tim Hortons filed a statement of defence with the Quebec Superior Court that inverted the blame: The Globe and Mail reported on June 15 that the company's defence attributed weaker franchise performance to the franchisees themselves, while also disclosing details of how the chain structures its pricing across the system.

That defence document is consequential beyond this litigation. Franchise pricing architecture is typically held close; once filed in court it becomes part of the public record, giving competitors, regulators, and future plaintiffs a window into how Tim Hortons sets margins. The franchisee dispute also feeds directly into the non-dairy surcharge class action — the same pricing data that franchisees say demonstrates corporate overreach is now being cited by consumer plaintiffs as evidence of unfair markups.

The franchisor-franchisee tension at Tim Hortons has a documented history. The chain's parent, Restaurant Brands International, has faced franchisee organizing efforts and public disputes in Canada before, typically centering on the allocation of costs — advertising levies, renovation mandates, supply chain markups — between the corporate entity and store operators. The Quebec suit is the most formalized escalation of that tension in recent years.

The Roll Up to Win Complication

A third, distinct legal action adds further texture. A Quebec judge authorized a separate class action against Tim Hortons related to Roll Up to Win promotional emails sent in error to program participants. The Times Colonist reported in June 2025 that the authorization was limited to Quebec customers. The core claim involves participants who received erroneous communications about the promotion — a narrower consumer harm than the pricing suits, but one that adds to the reputational and legal overhead the company is managing in the province.

Tim Hortons has also previously faced a class action tied to privacy breaches involving its mobile application, though that proceeding is distinct from the current cluster of Quebec cases.

What the Legal Geography Means

Quebec's civil procedure framework — specifically its relatively plaintiff-friendly class action authorization threshold under the Code of Civil Procedure — makes the province a natural venue for consumer collective actions. Authorization requires only that the applicant establish a defensible cause of action and that the case raises common questions; the evidentiary bar is lower than certification in common-law provinces. That procedural reality partly explains why multiple plaintiffs have chosen Quebec courts, and it is why authorization orders, while meaningful, should not be read as prejudging the merits.

For Tim Hortons, the convergence of three authorized or pending class actions in a single province, alongside an active franchisee lawsuit whose defence has now entered the public record, creates a legal environment that will be difficult to manage quietly. Discovery in the franchisee case may produce additional documents relevant to the consumer pricing suits. Counsel on both sides will be watching for that overlap.

Restaurant Brands International has not issued a public statement addressing the combined litigation picture as of June 20, 2026.
