Write your request
State plainly that you want the Adt Canada 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]”).
Mail it with tracking
Mail the letter by certified mail to the Burnaby address in the next section, and keep the tracking number.
File the delivery record
It shows the date Adt Canada received your letter. Check your next statement: no Adt Canada charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a security or identity-protection subscription
Security subscriptions often auto-renew and monitored plans can sit on a fixed contract term, so it matters when the request reaches the provider and whether it covers every device or location.
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.
