How to cancel Interac by mail
Start with your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Interac is the easiest one to set aside.
Draft the request
Postbye turns the request into a finished English letter headed “Subject: Cancellation Request – [your name]”: close the Interac account, stop every charge and reply in writing.
Mail it with tracking
Post it by certified mail to Interac in Toronto, Canada, using the exact address below, and note the tracking number.
File the delivery record
Keep the tracking record with your copy of the letter. If Interac bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Interac cancellation letter goes
Written requests to Interac go to P.O Box 45, Suite 2400, M5J 2J1 Toronto, Canada.
“P.O Box 45” is a post-office box or mail-sorting line, so it takes post and not couriers: certified mail is the right way to reach it.
The letter greets the reader with “To Whom It May Concern,”; your own details sit under the labels Account holder, Billing address on file and Email on file.

Before you cancel Interac, check these
- 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.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
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.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
Interac's own site is interac.ca. Check its account and billing area first to see whether the plan is billed by Interac itself or by a partner.
