How to cancel Comm Stream by mail
Gather your account details
Have the email address on the account, the plan name and, if you can find it, the billing partner shown on your latest statement to hand. The details in the letter need to match what Comm Stream has on file.
Write the cancellation request
Your Postbye letter to Comm Stream 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 it with proof of delivery
Use certified mail for the R3T 1L7 Winnipeg address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date Comm Stream was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Comm Stream cancellation letter goes
Comm Stream takes its post at Buffalo Place 1479, Unit#108, R3T 1L7 Winnipeg, Canada, which is where a cancellation letter belongs.
Copy the postal code R3T 1L7 exactly: it is what routes the letter to Manitoba, Canada.
Inside, the salutation reads “To Whom It May Concern,”, followed by your details under Account holder, Billing address on file and Email on file.

Every address we hold for Comm Stream, with the envelope wording
Before you cancel Comm Stream, check these
- Bundles and add-on channels can be billed separately from the base plan. Ask for every line to be cancelled.
- Check the billing date on your statement and send the request well before it, so the cancellation lands inside the current period.
- If an app store, phone carrier or TV provider bills you, the service itself cannot cancel it. Cancel with the billing partner as well.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a streaming or entertainment subscription
Streaming plans renew silently each month, and many are billed by a partner such as an app store or a TV provider rather than the service itself, so the request has to reach whoever actually bills you.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
