This guide shows where to cancel Rogers (Internet/TV/Phone) in Canada, with links to official sources.
Rogers notes cancellation is handled by an agent who reviews the account and discusses options, and that charges like unreturned equipment or early cancellation fees may apply depending on your plan.
Before you contact them: write down your desired cancellation date and list all rental equipment (modem, TV boxes).
After canceling: follow Rogers instructions to return rental equipment and keep your receipt/tracking number.
