- Key issue
- Whether a proposed price-fixing class action could be certified under the Class Proceedings Act, 1992 where the plaintiff lacked evidence that the alleged conspiracy caused harm to purchasers in Canada.
- Outcome
- The certification motion was dismissed because the plaintiff failed to establish some basis in fact for an identifiable class, common issues, preferable procedure, and a suitable representative plaintiff in the Canadian context.
- Why it matters
- If you are considering joining or launching a class action in Ontario, this decision is a clear reminder that foreign regulatory findings alone are not enough — you need evidence of harm in Canada.
Legal principle
The rule from this case
To have a class action certified in Ontario, a plaintiff must show 'some basis in fact' for each of the certification requirements under the Class Proceedings Act, 1992. That is not a high bar on its own, but it is a real one. The court must see actual evidence — not just plausible theory — that there is an identifiable class, that common issues predominate, that a class proceeding is the preferable procedure, and that the proposed representative plaintiff can adequately represent the class. Where the alleged wrongdoing involves a foreign price-fixing conspiracy, the plaintiff must connect that conduct to harm suffered by people in Canada. Press releases from foreign regulators, media reports, and hypothetical expert opinions about possible overcharges are not enough. The court needs some basis in fact that the conspiracy actually reached Canadian purchasers — whether they bought directly, indirectly through a supply chain, or as so-called 'umbrella purchasers' who paid inflated prices from non-conspirators.
Important limits
What this does not mean
This decision does not mean that price-fixing class actions can never be certified in Ontario, or that foreign regulatory investigations are irrelevant. Courts have certified competition class actions in the past, and foreign enforcement actions can form part of a broader evidentiary record. The key is that they cannot carry the entire weight of the certification motion on their own. This case also does not establish that indirect or umbrella purchasers are automatically excluded from class actions. Those categories of plaintiffs can be included in a properly constructed class — but only when the plaintiff can show some basis in fact that common issues predominate across that diverse group, and that the supply chain complexity does not make the case unmanageable. Where the proposed class is so broad that members cannot reliably self-identify, and where individual issues would overwhelm common ones, certification will be refused.
Can a Price-Fixing Class Action Be Certified Without Evidence of Harm in Canada?
No — an Ontario court will refuse to certify a class action if the plaintiff cannot show some basis in fact that the alleged price-fixing conspiracy actually caused harm to purchasers in Canada. Foreign regulatory investigations and media coverage of wrongdoing abroad are not a substitute for Canadian evidence.
In Parris v. Firmenich International SA et. al., 2026 ONSC 3922 (CanLII), the Ontario Superior Court of Justice dismissed a certification motion in a proposed price-fixing class action. The court found that the plaintiff had not met the evidentiary threshold for any of the key certification requirements under the Class Proceedings Act, 1992.
What Does ‘Some Basis in Fact’ Actually Mean?
The ‘some basis in fact’ standard is the evidentiary threshold a plaintiff must meet on a certification motion — it sits somewhere between a bare pleading and a full trial. The plaintiff does not have to prove the case at this stage, but they do have to put forward actual evidence supporting each certification requirement.
The Supreme Court of Canada set out this framework in Hollick v. Toronto (City) and it has been consistently applied since. Courts look at whether there is real evidence — not just logical inference or expert speculation — that the proposed class exists, that common questions predominate, and that a class action is the best way to resolve the dispute. When that evidence is missing, certification fails.
Who Can Be Included in a Price-Fixing Class?
Proposed classes in price-fixing cases often include three groups: direct purchasers (who bought straight from the alleged conspirators), indirect purchasers (who bought through a supply chain), and umbrella purchasers (who bought from non-conspirators but allegedly paid inflated prices because of the conspiracy’s effect on the market). Each of these groups raises different legal and factual questions.
The court in this case found that combining all three groups into a single class created serious problems. Supply chain complexity made it difficult to determine who actually paid an inflated price, what products were affected, and whether class members could reliably identify themselves as belonging to the class. Following the approach in Sun-Rype Products Ltd. v. Archer Daniels Midland Co., the court found that overbreadth and the dominance of individual issues undermined the proposed class structure.
Can Foreign Regulator Findings Prove a Canadian Conspiracy?
No — press releases and decisions from foreign competition regulators are hearsay, and on their own they cannot establish some basis in fact that a conspiracy harmed Canadian purchasers. The court distinguished the approach taken in other cases and found that the foreign enforcement materials here did not bridge the gap between alleged wrongdoing abroad and harm in Canada.
The plaintiff’s expert offered a hypothetical analysis of potential overcharges and how they might have flowed through supply chains into Canada. The court found this was not enough. A hypothetical model built on assumed facts is not evidence that the conspiracy actually reached Canadian buyers or caused them to pay more than they otherwise would have.
Is a Class Action the Preferable Procedure When Regulators Are Involved?
Not necessarily — especially when individual damages are small and regulatory bodies already have powers to investigate and remedy the harm. The court weighed the existence of foreign regulatory investigations and the minimal individual damages each class member might recover, and found that the plaintiff had not established that a class proceeding was superior to other available means of resolving the dispute.
The Class Proceedings Act, 1992 requires the court to consider whether a class action is the preferable procedure, taking into account both the superiority of the class format and whether common issues predominate over individual ones. Where those conditions are not met — particularly when the regulatory landscape already addresses the alleged harm — the preferable procedure requirement will not be satisfied.
Practical Takeaways for Prospective Class Action Plaintiffs
If you are considering participating in or launching a class action in Ontario, this decision highlights several important red flags and action items:
- Canadian evidence is essential. Foreign regulatory findings, no matter how significant, do not automatically establish that Canadians were harmed. Your legal team needs to gather evidence of harm within Canada.
- Class definition matters. A proposed class that is too broad — mixing direct, indirect, and umbrella purchasers without a clear way for members to self-identify — will face serious challenges at certification.
- Expert evidence must go beyond hypothesis. An expert opinion that assumes the conspiracy affected Canada, without underlying data to support that assumption, is unlikely to satisfy the ‘some basis in fact’ standard.
- Preferable procedure is a real hurdle. If individual damages are small and regulators are already active, the court will scrutinize whether a class action actually serves the interests of justice better than other options.
- Act early with experienced counsel. Certification motions are complex and evidence-intensive. Getting the evidentiary record right from the start is critical.

How Does This Affect Consumers Who Think They Overpaid?
If you believe you paid inflated prices because of a price-fixing conspiracy, this decision does not close the door on recovery — but it does underscore that any class action on your behalf needs to be built on solid Canadian evidence. A well-structured claim with proper evidentiary support can still succeed at certification.

FAQ
Frequently asked questions
If certification is refused, the proposed class action cannot proceed as a group claim. Individual plaintiffs may still pursue their own claims separately, but the economies of scale that make class actions worthwhile are lost. In some cases, plaintiffs may seek to amend their materials and bring a fresh certification motion.
Certification motions in complex cases can take months or even years to prepare and argue, depending on the volume of evidence, the number of parties, and the court's schedule. The evidentiary record — including expert reports and documentary evidence — must be assembled well before the hearing.
Yes, indirect purchasers can be included in a price-fixing class action in Ontario, but the plaintiff must show some basis in fact that common issues predominate across the class and that the supply chain complexity does not make the case unmanageable. Courts will scrutinize whether indirect purchasers can reliably self-identify as class members.
