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

The case centers on a common consumer complaint: coffee chains charging premiums for oat milk and other plant-based alternatives that exceed what those alternatives actually cost the company. Internal pricing data revealed in a separate proceeding showed that Tim Hortons charged customers 50 cents for a non-dairy swap while the product cost the company only 28 cents in eastern Quebec. That gap forms part of the plaintiffs' argument that the pricing was unfair. When a Quebec Superior Court judge authorizes a class action, it means the court has found the lawsuit raises questions of law or fact that are common across a group of people — and that those questions are worth settling collectively rather than one case at a time. Authorization is not a finding that Tim Hortons actually did anything wrong; it clears the procedural path for the lawsuit to move forward.

Franchisees vs. Head Office

The non-dairy milk suit is one of several legal fronts. Fifteen Quebec franchisees filed suit against Tim Hortons in 2024, alleging that corporate decisions on pricing, supply, and operations had cut into their profits by roughly CA$27 million. In June 2026, Tim Hortons filed a response in Quebec Superior Court that shifted blame back to the franchisees themselves, The Globe and Mail reported, while also revealing details about how the chain structures its pricing across its system.

That defence document carries weight beyond this single lawsuit. Franchise pricing structure is usually confidential; once it enters the court record, it becomes public and gives competitors, regulators, and future plaintiffs a clearer picture of how Tim Hortons sets profit margins. The franchisee dispute also connects directly to the non-dairy surcharge class action. The same pricing data that franchisees cite as evidence the corporation was squeezing them is now being used by consumer plaintiffs as proof of unfair markups.

Tension between Tim Hortons and its franchisees is not new. Restaurant Brands International, the company's parent, has dealt with franchisee complaints and public disputes in Canada before, usually centered on how costs — advertising fees, mandatory renovations, supply chain markups — are split between the corporate head office and individual store owners. The Quebec franchisee suit represents the most formal escalation of that conflict in recent years.

The Roll Up to Win Complication

A third legal action adds another layer. A Quebec judge authorized a separate class action against Tim Hortons related to Roll Up to Win promotional emails sent to program participants by mistake. The Times Colonist reported in June 2025 that the authorization applied to Quebec customers. The claim involves participants who received incorrect messages about the promotion — a narrower form of consumer harm than the pricing disputes, but one that adds to the legal and reputation burden Tim Hortons is managing in the province.

The company has also faced a class action tied to privacy breaches in its mobile application, though that case is separate from the current wave of Quebec litigation.

Why Quebec, Why Now

Quebec's civil court system — in particular, its relatively accessible threshold for approving class actions under the Code of Civil Procedure — makes it an attractive jurisdiction for consumer lawsuits. To authorize a class action, a Quebec judge needs only to be satisfied that the case raises a defensible legal claim and that common questions apply to the group; the bar is lower than in common-law provinces. That procedural advantage explains why multiple plaintiffs have chosen Quebec courts, and it is why authorization orders, while legally significant, should not be read as proof of guilt.

For Tim Hortons, the combination of three authorized or pending class actions in one province, alongside the franchisee lawsuit whose defence documents are now public, creates a complex legal environment that will be hard to manage out of the spotlight. Documents uncovered during the franchisee case may turn up evidence relevant to the consumer pricing suits. Both sides' lawyers will be watching for that overlap.

Restaurant Brands International has not made a public statement about the full scope of its legal challenges in Quebec as of June 20, 2026.
