How to cancel Fido by mail
Start with your account details
Put the account number, the phone number or service address being cancelled and the name on the account in front of you before you write: the request to Fido is only as good as the details it quotes.
Write your request
The letter asks Fido to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Cancellation Request – [your name]”. Postbye fills it in from our English template.
Post it with proof of delivery
Take the letter to the post office and ask for certified delivery to M4W 1G9 Toronto. Keep the tracking number it gives you.
Hold on to the receipt
File the receipt with the letter. A Fido 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 Fido cancellation letter goes
Written requests to Fido go to Bloor Street East 333, M4W 1G9 Toronto, Canada.
The postcode M4W 1G9 belongs to Ontario, Canada, so this is where the envelope is delivered.
Inside, the salutation reads “To Whom It May Concern,”, followed by your details under Account holder, Billing address on file and Email on file.

Cancelling a phone or internet plan
Phone and internet providers tie cancellation to contracts, equipment balances and notice periods, so the request should name the exact line or service and ask for a final bill in writing.
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.
