Critical Border-Crossing Tips
- Documents: Valid passport, Enhanced Driver’s License (EDL), NEXUS card, or FAST card. Birth certificate + photo ID no longer sufficient for adults.
- Wait times: Check CBP (US) or CBSA (Canada) for real-time queue lengths. Peace Bridge often busiest; Lewiston–Queenston sometimes faster for NEXUS.
- Traffic: QEW (Queen Elizabeth Way) into Toronto congested weekday mornings (7–9 AM) and evenings (4–6 PM).
- Rental cars: Confirm cross-border permission and insurance with rental agency.
- Goods/alcohol/tobacco: Know personal exemption limits (CAD $800 for 48+ hr stay; alcohol/tobacco limits apply).
Non-Driving Options
- Train: Amtrak Maple Leaf (NYC–Toronto) stops at Buffalo–Exchange St. and Niagara Falls; ~4h 30m Buffalo→Toronto.
- Bus: Megabus, Greyhound, or Coach Canada (~2h 30m + border time).
- Flight: Buffalo (BUF) → Toronto (YYZ) ~45 min air, but airport overhead makes it slower door-to-door.
For most travelers, driving via the Peace Bridge is the default choice—shortest distance, direct highway connection, and 24/7 operation. With NEXUS and off-peak timing, door-to-door can be under 2 hours.
