Windsor Airport Car Rentals: Best Rates & Zero Hidden Fees

Your valid US driver's license works perfectly in Windsor—no International Driving Permit (IDP) required. Just ensure your license is current and not expired. If you plan to drive extensively across Canada or rent for extended periods, carrying an IDP as backup is helpful but never mandatory for US citizens visiting Ontario.

Ontario doesn't legally mandate winter tires for visitors, but most rental companies in Windsor automatically equip vehicles with all-season tires. For serious winter driving (December–March), request winter tires specifically—many agencies offer them for CAD $10–15/day extra. Winter tires significantly improve safety on icy roads and during lake-effect snowstorms common near the Great Lakes region.

Driving in Windsor feels familiar—it's right-hand drive like the US. Key differences: you can turn right on red lights unless posted otherwise (same as most US states). Speed limits are posted in km/h (100 km/h ≈ 62 mph on highways). Ontario is strict about distracted driving—hands-free only, with fines up to CAD $1,000. Pedestrians always have right of way at crosswalks, and failing to yield carries heavy penalties.

Most major rental companies (Enterprise, Hertz, Avis, Budget) allow US-Canada border crossing, but you must declare this at pickup. Some companies charge a cross-border fee (CAD $5–15/day) or restrict specific vehicle classes. Always carry your passport, rental agreement, and proof of insurance. One-way rentals across the border typically incur substantial drop-off fees (CAD $200–500+).

Most US auto insurance policies extend to Canada, but contact your insurer beforehand to confirm coverage limits and obtain a Canadian insurance card (sometimes required). Credit card rental coverage typically applies in Canada, but verify your card's terms—some exclude certain vehicle types or have lower coverage limits abroad. Rental companies offer CDW/LDW at CAD $20–30/day as backup if your personal coverage is insufficient.

The Detroit-Windsor crossing (via Ambassador Bridge or Detroit-Windsor Tunnel) is North America's busiest commercial border. Wait times range from 10 minutes to over an hour—check real-time wait apps like CBP Border Wait Times or CBSA website before crossing. Have passports, rental documents, and return itinerary ready. Declare all goods, alcohol, and tobacco. CBP and CBSA officers may ask about trip purpose, duration, and accommodations.
