What must an insured provide if they wish to cancel their automobile insurance?

To cancel automobile insurance in Ontario, the insured is required to provide a notice to their insurance provider. This notice serves as a formal communication that expresses the insured's intention to cancel the policy. It is essential for the insurer to receive this notification in order to process the cancellation effectively and update their records accordingly.

Providing a notice ensures that there is a clear record of the cancellation request, which is important for both parties in case of future disputes or misunderstandings. Depending on the insurer's policies, the notice may need to include specific information such as the policy number, the effective date of the cancellation, and possibly a signature.

The other options do not align with the standard procedure for cancellation. A written request submitted through certified mail might be an unnecessary formality that most insurers do not require. Optionally scheduling a call with a customer service representative could lead to miscommunication, and simply not providing notice at all can lead to ongoing charges and complications. Therefore, the requirement for the insured to provide a notice to the insurance provider is critical for proper processing of the cancellation.
