Buffalo, NY → London, ON

Your drive from Buffalo, NY to London, Ontario is a straightforward 156-mile journey that will take you approximately two hours and thirty-seven minutes, primarily following the Queen Elizabeth Way (QEW) north and then transitioning to the 403 and 401 highways once you cross into Canada. You'll begin by heading north from Buffalo on I-190, which quickly merges onto the Niagara-Lewiston Bridge or the Whirlpool Rapids Bridge, both of which cross the Niagara River and serve as your gateway into Ontario. These border crossings offer your first dramatic landscape shift—the moment you leave the American side, you're immediately greeted by views of the Niagara Gorge's impressive rock formations and rushing waters below. Have your passport or travel documents ready at customs, as this crossing requires proper identification to proceed into Canada.

Once across the border, the QEW hugs the northern shore of Lake Ontario, providing scenic water views for much of your journey, particularly around the Niagara region where you'll pass through wine country and glimpse the distant escarpment. The terrain gradually transitions from the dramatic gorge landscape into gentler, more rolling countryside as you continue westward through the Golden Horseshoe region. You'll drive through or near several notable communities, including Niagara-on-the-Lake and St. Catharines, before the landscape opens up into broader agricultural plains characteristic of southwestern Ontario.

The final portion of your route takes you inland on Highways 403 and 401, moving away from the lake and into predominantly rural farmland as you approach London. The elevation remains relatively modest throughout this entire drive, with no significant mountain passes or challenging terrain to navigate. Late spring through early fall represents the most pleasant time to make this drive, when the roads are clear, visibility is excellent, and you can enjoy the Niagara region's pastoral scenery. Winter driving can be treacherous along this corridor, particularly on the bridge crossings and when crossing into the more exposed rural sections, so extra caution and preparation are essential during the colder months.
