How to cancel Fibrestream by mail
Start with your account details
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 Fibrestream has on file.
Prepare the letter
Your Postbye letter to Fibrestream 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.
Mail it with tracking
Send the letter to the Toronto mailing address shown below by certified mail. Keep the tracking number safe.
File the delivery record
It shows the date Fibrestream received your letter. Check your next statement: no Fibrestream charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Fibrestream cancellation letter goes
Fibrestream can be reached by post at Adelaide Street West 530, M5V 1T5 Toronto, Canada.
Copy the postal code M5V 1T5 exactly: it is what routes the letter to Ontario, Canada.

Before you cancel Fibrestream, check these
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
