How to cancel Canada Post by mail
Start with your account details
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Canada Post holds, so the request can be matched to your account.
Prepare the letter
Your Postbye letter to Canada Post asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Cancellation Request – [your name]”. It comes from our English template.
Post it with proof of delivery
Post it by certified mail to Canada Post in Ottawa, Canada, using the exact address below, and note the tracking number.
Keep the delivery receipt
File the receipt with the letter. A Canada Post charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Canada Post cancellation letter goes
Written requests to Canada Post go to Riverside Drive 2701, K1V 1J0 Ottawa, Canada.
The postcode K1V 1J0 belongs to Ontario, Canada, so this is where the envelope is delivered.
The letter is addressed “To Whom It May Concern,” and its details block uses the labels Account holder, Billing address on file and Email on file.

Before you cancel Canada Post, check these
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
