Information, not a service
Articles describe typical winter driving around Kanata and Ottawa and summarize public rules as of the date on the page. They are not legal advice, not an inspection, and not a promise that a tire will fit your vehicle.
The calculator compares two sizes mathematically. It does not know your car's clearance, load, brakes, or speed rating. A percentage on the screen is not an instruction to mount that tire.
Local rules change
Ontario and Quebec can amend tire rules. Check the official text before you rely on a summary about studs, tread, or a seasonal requirement. Shop work, torque, and repairs belong with a licensed business and the vehicle manual.
