Mississauga, ON → Windsor, ON

Your journey from Mississauga to Windsor takes you on a straightforward 251-mile trek through the heart of Southern Ontario, primarily following the Queen Elizabeth Way (QEW) and the Gardiner Expressway before merging onto the Macdonald-Cartier Freeway (Highway 401). This approximately four-hour-and-twelve-minute drive is one of Canada's most frequently traveled corridors, connecting the Golden Horseshoe region with the southwestern peninsula. The route is well-maintained and heavily trafficked, so you'll want to plan around rush hours in the Greater Toronto Area if you're departing in the early morning or late afternoon.

As you leave the Mississauga area, you'll descend from the higher elevations of the Niagara Escarpment and transition into the gentler, flatter landscape that characterizes much of the Ontario lowlands. Passing through or near Hamilton, you'll notice the industrial character of the region gradually give way to more agricultural terrain as you head westward. The landscape becomes increasingly rural as you progress past London and into the fertile farmland of southwestern Ontario, with rolling fields, orchards, and forest patches replacing the urban sprawl you left behind. This transition from metropolitan density to pastoral countryside happens gradually and is one of the subtle pleasures of this drive.

You'll pass through or near several notable communities along the way, including Hamilton, the steel city sitting at the western end of Lake Ontario, and London, a mid-sized university town that marks the approximate halfway point of your journey. The final stretch into Windsor brings you through increasingly agricultural landscape as you approach Canada's gateway to Detroit and the U.S. border.

For the most pleasant driving experience, aim for late spring through early fall when road conditions are optimal and visibility is excellent. Winter driving on this route requires particular caution, as ice and snow can make the QEW and Highway 401 treacherous, especially during lake-effect snow events. Spring and fall offer comfortable temperatures and generally clear roads, making these seasons ideal for this straightforward but rewarding southwestern Ontario corridor.
