How to cancel Cibc by mail
Collect the details you need
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Cibc has on file.
Put the request in writing
Your Postbye letter to Cibc 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 the letter
Use certified mail for the M5L 1G5 Toronto address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
The receipt dates your request. Look at your next statement for any Cibc charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Cibc cancellation letter goes
Cibc lists Bay Street 199, M5L 1G5 Toronto, Canada as its mailing address.
The envelope is going to Toronto in Ontario, Canada, so the postcode M5L 1G5 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 Cibc, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
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 phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
