The Equifax & TransUnion Class Action: What Credit Report Errors Mean for Your Mortgage

A proposed class action filed this spring is putting Canada's two big credit bureaus — Equifax and TransUnion — under an uncomfortable spotlight. The allegation at its core is one I see the consequences of regularly as a mortgage broker: credit reports that contain errors, and the real financial damage those errors do to ordinary people.

Here's what the lawsuit is about, what's actually been decided so far (less than the headlines suggest), and — most practically — what you should do about your own credit file before you're sitting across from a lender.

What the Lawsuit Alleges

In May 2026, law firm Klyden Legal filed a proposed class action against Equifax and TransUnion in the Quebec Superior Court, announced in an official release. The proposed class covers consumers whose personal information in their Equifax or TransUnion credit file was false or inaccurate at any time since May 5, 2023.

The lead example is memorable: one of the representative plaintiffs, Kevin Villeneuve, received alerts that a new mortgage had appeared on his credit file — except the mortgage belonged to a different Kevin Villeneuve, whose information had been mixed into his file. If your name is common, that scenario probably doesn't feel far-fetched.

The filing seeks $5,000 in damages plus $5,000 in punitive damages per class member — the source of the "$10,000 per Canadian" headlines, as covered by Daily Hive. Court documents and coverage cite data suggesting credit-file errors affect millions of files, with many taking multiple correction requests to fix.

Why a Mortgage Broker Cares About This

Because credit-file errors don't wait for a lawsuit to hurt you — they hurt you the day you apply for a mortgage. In my work I see how errors play out at the worst possible moment:

• A wrong late payment or a stranger's debt can drag your score below a lender's threshold — turning a prime-rate approval into a decline, or into a more expensive alternative-lender file.
• A debt that isn't yours inflates your ratios. Lenders qualify you on your debts; a mixed file can shrink your buying power on paper by hundreds of dollars a month.
• Errors surface mid-transaction. Discovering a file problem after you've made an offer, with a financing condition ticking, is exactly the stress you don't want. Disputes take time — sometimes more than one round.

The lawsuit will take years to resolve. Your credit file matters this year — so the practical response is to check it yourself, now, when there's no deadline attached.

How to Check Both of Your Credit Reports (Free)

• Check both bureaus. Equifax and TransUnion keep separate files, and lenders may pull either — an error can live on one and not the other. Both offer free online access to your own report.
• Read the boring parts. Verify every account is actually yours, balances look right, closed accounts show closed, and your addresses and employers are really yours (mixed files often show a stranger's address first).
• Checking yourself doesn't hurt your score. Looking at your own report is a "soft" inquiry — check as often as you like.
• Dispute in writing, keep records. Both bureaus have formal dispute processes; the Financial Consumer Agency of Canada explains your rights and the steps on its credit report guide.

Found an Error and a Mortgage Is on the Horizon?

Don't panic — plan. This is a routine part of my job: we look at what the error is, how it affects your file at each bureau, which lenders pull which report, and whether the fix or the mortgage should come first. Sometimes the right move is disputing and waiting sixty days; sometimes it's choosing a lender who reads the file the right way today. That's a strategy conversation, and it's free: start with my Mortgage Plan tool or just send me a message.

And if your credit has taken real hits — beyond errors — there's a path for that too: see alternative and private lending, always with an exit plan back to prime.
