Which Is Farther from Toronto by Highway: Buffalo or Detroit?

Detroit is significantly farther.

• Toronto → Buffalo, NY: ~100 miles (160 km), ~1.5–2 hours via QEW → I-190
• Toronto → Detroit, MI: ~235 miles (378 km), ~3.5–4 hours via Highway 401 → Ambassador Bridge or Detroit–Windsor Tunnel

Why the Difference Matters

• Day trips: Buffalo is an easy same-day excursion; Detroit requires an early start or overnight stay.
• Border crossing: Both cross the Niagara River (Buffalo) or Detroit River (Detroit); wait times vary—check CBP / CBSA apps.
• Traffic patterns: Highway 401 through the GTA and around Windsor can add 30–60 minutes at rush hour.

If you're measuring highway distance from Toronto, Detroit is more than twice as far as Buffalo.
