How to cancel The Canadian Encyclopedia by mail
Start with your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. The Canadian Encyclopedia can only act on a request it can match to an account.
Write the cancellation request
Ask The Canadian Encyclopedia to cancel the account, stop all further charges and confirm in writing. Postbye prepares the letter from our English template, with the subject line “Subject: Cancellation Request – [your name]”.
Mail it with tracking
Use certified mail for the M5C 1J3 Toronto address in the next section, so the post office records the delivery. Write down the tracking number.
Hold on to the receipt
It shows the date The Canadian Encyclopedia received your letter. Check your next statement: no The Canadian Encyclopedia charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

How cancelling by mail works
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
