How to cancel Wave by mail
Note 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 Wave is only as good as the details it quotes.
Set out the request
State plainly that you want the Wave account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Cancellation Request – [your name]”).
Post the letter
Post it by certified mail to Wave in Toronto, Canada, using the exact address below, and note the tracking number.
Keep proof the letter arrived
File the receipt with the letter. A Wave 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 Wave cancellation letter goes
Wave can be reached by post at 155 Queens Quay East, Suite 500, Box 3, M5A 0W4 Toronto, Canada.

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 Wave, 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
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.
