Critical Factors

• Border Crossing: Ambassador Bridge (trucks) vs. Tunnel (cars). Check CBP wait times. Nexus/FAST cards save time.
• Traffic: Toronto bypass (401/403/407) can add 1–2 hrs rush hour. The 407 ETR (toll) is faster but requires transponder/account.
• Weather: Lake-effect snow (Dec–Mar) on 401 near London; winter tires mandatory in ON.
• Documents: Passport / Enhanced DL / NEXUS. Check Canada entry rules.

Pro Tip: Break it into two days (stop in London, ON or Toledo) for a relaxed trip. Fuel up in US (cheaper).
