How to cancel Air Canada by mail
Start with your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Air Canada is only as good as the details it quotes.
Set out the request
Your Postbye letter to Air Canada 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
Take the letter to the post office and ask for certified delivery to H4Y 1H4 Saint-Laurent. Keep the tracking number it gives you.
Hold on to the receipt
Once the letter is delivered, the date on the receipt is the date Air Canada was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Air Canada cancellation letter goes
Air Canada can be reached by post at 7373 Côte-Vertu Boulevard West, H4Y 1H4 Saint-Laurent, Canada.
The envelope is going to Saint-Laurent in QC, Canada, so the postcode H4Y 1H4 must be on the front.
Inside, the salutation reads “To Whom It May Concern,”, followed by your details under Account holder, Billing address on file and Email on file.

Before you cancel Air Canada, check these
- 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.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
