Cancellation Onstar: Simple Process
What is Onstar
OnStar is a subscription-based connected-vehicle service available in Canada that provides emergency and safety response, stolen-vehicle assistance, roadside support, in‑vehicle apps and infotainment, Wi‑Fi hotspot and internet services, and hands‑free driver assistance under the Super Cruise brand. Services are delivered via the vehicle’s built‑in telematics system or via the OnStar Guardian smartphone app and are billed on a subscription basis.
How to cancel Onstar
- By phone: Call 1‑888‑4‑ONSTAR (1‑888‑466‑7827) and tell the agent you want to cancel your OnStar plan. Have your account details and VIN ready.
- In‑vehicle: Press the blue OnStar button in your vehicle and request cancellation with the advisor; note the date/time and confirmation number if provided.
- Online: Sign in to your My Account at onstar.com, go to “My Plans,” select the plan and choose “cancel my plan.”
- By written notice (recommended if you want proof): Send a signed cancellation letter with account details and VIN via registered mail to the OnStar Member Services address (see Address section below). Keep the tracking receipt and a copy of the letter.
What happens when you cancel
When you cancel, OnStar will stop future renewals of the cancelled plan; services generally remain active through the end of your current billing period. After the service period ends you will no longer have access to subscription features tied to the plan, including emergency‑response features or Wi‑Fi if those were part of the cancelled plan. Account records and billing history are retained by OnStar in accordance with their terms and privacy policy; consult OnStar’s terms for details on data retention and account management.
Will I get a refund?
Refund eligibility depends on how you paid and whether the subscription was included in your vehicle purchase or lease. If you cancel mid‑billing period there is no pro rata refund for the remainder of that billing cycle, but your services generally continue until the end of the period. If you prepaid for whole months or days and the plan was not included in the vehicle purchase or lease, you may be eligible for a refund of unused full months and remaining days. No refunds are available for prepaid plans that were included in the vehicle purchase or lease. Also note there is no general 14‑day cooling‑off right under Canadian rules for digital subscription services like OnStar; statutory cancellation rights that apply to certain contract types do not typically extend to digital subscriptions.

Your consumer rights in Canada
Canadian consumer protection laws provide different cancellation and cooling‑off rights depending on the type of contract. Typical 14‑day cooling‑off periods apply to certain direct or distance sales and specific contract types but do not generally apply to digital subscription services like OnStar. Federal Direct Sellers Harmonization rules give a 10‑day cancellation right for qualifying direct‑sales contracts after receiving the contract, but that does not normally cover subscription telematics services. Provincial consumer protection statutes (for example in Ontario) create cooling‑off rights for defined contract categories, but these rules likewise do not typically extend to in‑vehicle digital subscription plans. For contract‑specific rights and details, review your OnStar terms and any provincial rules that may apply to the way the subscription was sold.
Customer experiences
User feedback on OnStar in Canada is mixed. Many customers praise OnStar’s emergency and safety features - some describing the service as lifesaving when it helped locate or assist drivers with medical or cognitive emergencies. On the other hand, there are recurring complaints about difficulty cancelling (including continued billing after attempted cancellation), long phone waits and call transfers, delays or failures in roadside assistance, technical problems with apps and GPS, and instances of being charged despite no rendered service. These reports suggest good performance for core safety features for some customers, while administrative and support experiences can be inconsistent.
Documentation checklist
- Account number or OnStar member ID and vehicle VIN
- Your full name, phone number and email on file
- Last 4 digits of the payment card on file (for verification)
- Copy of your subscription invoice or proof of payment (showing prepaid months if applicable)
- Copy of vehicle purchase/lease documents (if subscription was included)
- Written cancellation request (if sending registered mail) and copy retained
- Call date/time, agent name and confirmation number (if provided)
- Registered‑mail tracking number and delivery receipt (if mailing)
Common mistakes
Common mistakes include relying on a verbal cancellation without getting a written confirmation or reference number, failing to record the date/time and agent details during phone cancellations, and not keeping proof of cancellation delivery. Another frequent error is assuming a refund will be issued for time remaining in a billing cycle - OnStar does not refund mid‑billing‑cycle but may refund prepaid unused full months/days only when the plan was paid separately (not included in the vehicle purchase/lease). Some customers also skip checking whether their subscription was a bundled feature of the vehicle purchase; bundled plans are generally not refundable. To avoid problems, document every step and keep copies of communications and receipts.
Comparative recap
| Method | Refund | Difficulty |
|---|---|---|
| Phone (1‑888‑4‑ONSTAR) | No pro rata refund for mid‑cycle; possible refund for prepaid unused full months/days if not part of vehicle purchase | Medium - High (reports of long waits and call transfers) |
| Blue OnStar button (in‑vehicle) | Same refund rules as phone | Variable (can be quick, but outcomes depend on agent and call handling) |
| Online (My Account → My Plans → cancel my plan) | Same refund rules; online cancellation may be simplest if your account is accessible | Low - Medium (generally straightforward but depends on account access and site functioning) |
| Registered mail (written notice) | Same refund rules; provides clear proof if dispute arises | Medium (requires time to prepare and mail, but provides documented proof of delivery) |
After cancelling
After you cancel, watch your bank or card statements for any unexpected charges and save all confirmation details. If you were told you would receive a refund for prepaid unused months or days, allow a reasonable processing time and follow up with OnStar if it does not appear. If billing continues after cancellation or you cannot get a satisfactory response, escalate by sending written notice via registered mail with your documentation, and consider filing a complaint with your provincial consumer protection office or your payment card issuer if you suspect unauthorized charges.
