Where to mail an Equifax Canada credit dispute
Mail your credit report dispute to: Equifax Canada Co., National Consumer Relations, Box 190, Jean Talon Station, Montreal QC H1S 2Z2. Include the completed Equifax dispute form and copies — never originals — of any documents that support your correction. Disputing by mail creates a paper trail that an online form does not, which matters if the error resurfaces later.

Key facts
- Include the completed Equifax dispute form with your mailing — it tells Equifax exactly which items you are challenging and why.
- Send COPIES of supporting documents (statements, letters from lenders, ID). Never mail originals — they are not returned.
- You can also dispute online through Equifax’s website, but mail gives you a physical paper trail of what you sent and when.
- Equifax and TransUnion are separate bureaus — if the error appears on both reports, you must dispute with each one separately.
- PostPal mails your dispute for $6 flat, printed and deposited with Canada Post the next business day — keep the Confirmation of Mailing email for your dispute records.
How to mail it, step by step

Pull your Equifax report and flag the errors

- 2
Complete the Equifax dispute form
Download the consumer dispute form from Equifax Canada’s website and fill in your identification details plus each disputed item. A clear, specific form gets investigated faster than a vague letter.

Attach copies of your supporting documents
Photocopy or scan statements, lender letters, or proof of payment that back up your dispute — and copies of two pieces of ID as the form requires. Keep every original at home.

Common questions
What is the mailing address for an Equifax Canada dispute?
Equifax Canada Co., National Consumer Relations, Box 190, Jean Talon Station, Montreal QC H1S 2Z2. Send the completed dispute form along with copies of any documents that support your correction.
Should I send original documents with my Equifax dispute?
No — send copies only. Equifax does not return documents, so photocopy or print duplicates of statements, lender letters, and ID, and keep every original at home.
Can I dispute online instead of by mail?
Yes, Equifax offers an online dispute option. Mail takes longer but creates a physical paper trail — you control exactly what was sent, and a Confirmation of Mailing from PostPal documents the date it went out, which can matter if the same error reappears.
Do I need to dispute with TransUnion too?
If the error appears on both reports, yes. Equifax and TransUnion are independent bureaus and do not share dispute results, so correcting your Equifax file does not fix your TransUnion file.
What should I include in my Equifax dispute package?
The completed Equifax dispute form, copies of two pieces of identification, and copies of documents supporting each disputed item — for example a statement showing the account was paid, or a letter from the lender. Keep a full copy of the package for yourself.
How do I prove when I mailed my dispute?
Keep dated proof of mailing alongside your copy of the package. When you send through PostPal, the Confirmation of Mailing email records the date your dispute was deposited with Canada Post — file it with your dispute records.
