Sonnet Insurance offers online auto insurance mainly in certain Canadian provinces, allowing you to get a personalized quote and buy a policy instantly. They have a usage-based program called Sonnet Shift that rewards safe driving with savings. Your policy payments work through a Recurring Payment Agreement, meaning you authorize Sonnet to charge your credit card or bank account automatically on a regular basis for your policy premium and fees. You can manage or update your payment info online, and the agreement continues unless you cancel or the policy ends.

Tips & Tricks for Canceling Sonnet auto policy
- Call repeatedly and ask to speak to a manager if the initial customer service representative is unhelpful or refuses to cancel.
- Submit a signed and dated cancellation letter including your policy number and desired cancellation date; send it via mail, fax, and email to the insurer and broker to cover all bases.
- No special cancellation form is typically needed; a simple written notice is usually sufficient even if the company claims otherwise.
- Escalate to your provincial insurance regulator if the insurer refuses to process your cancellation or give you a cancellation form.
- Use multiple communication channels (phone, email, fax, postal mail) to ensure your cancellation request is documented.
- Consider telling the insurer you sold the vehicle as an instant cancellation reason and follow up with written confirmation.
- Call your bank to stop future payments to the insurer as a backup to ensure billing stops.
- Timing advice: Start cancellation calls early and persist, as some users report needing multiple weeks and calls to finalize cancellation.
- Watch for gaps in coverage if switching insurers; overlap policies for a day or two if possible to maintain continuous coverage.
- Be firm and clear about your intention to cancel and avoid getting sidetracked by offers to stay or renegotiate.

Sonnet auto insurance allows you to cancel your policy at any time, but the policy must be in good standing with no overdue payments. Be aware that if you cancel mid-term, you may be charged a short-rate cancellation fee, which is a penalty that decreases the closer you are to the policy renewal date. Also, if you have Accident Forgiveness, you will lose that benefit when cancelling, which could lead to higher premiums with a new insurer.
Before cancelling your Sonnet auto policy, keep in mind that you will lose access to your auto insurance coverage from the cancellation date, which means your vehicle will no longer be insured through Sonnet. You can cancel your policy anytime by logging into your online account, selecting the policy, and choosing to cancel, but cancellations cannot be backdated, so be sure to choose an appropriate cancellation date. If you cancel before your policy's end date, particularly in provinces like Ontario, Quebec, New Brunswick, Nova Scotia, and P.E.I., a short rate cancellation fee may apply, which could affect any refund or amount owed. Also, if you choose not to renew your policy at the renewal date, there is no cost to cancel. Always confirm your balance or refund will be detailed in an email from Sonnet within two business days after cancellation.
