COVID-19 has made this a challenging time for some of our family and customers to get clear information. That's why we created this page-to give you a one-stop spot for information when it comes to your GMC vehicle questions in Hanover Ontario.

Whether you have questions about your vehicle or you need to discuss financial issues, or other resources, we've compiled answers to as many questions as we can.


If you have questions about your current Buick vehicle you can call our Customer Care Centre at 1-800-263-3777 (1-800-263-3830 for TDD users) or get connected by simply clicking to chat.
