Windsor, ON → Mississauga, ON

Your journey from Windsor to Mississauga spans approximately 251 miles and takes just over four hours, making it one of Ontario's most straightforward cross-province drives. You'll primarily follow the Queen Elizabeth Way (QEW) and Highway 401, two of Canada's busiest and most well-maintained corridors. The route begins by taking you east from Windsor through the heart of Ontario's most densely populated region, passing through some of the country's most important industrial and commercial centers. This is a drive that rewards careful planning, as you'll be sharing the road with significant truck traffic and commuter vehicles, particularly during peak hours.

Starting from Windsor, you'll head northeast through relatively flat farmland and suburban sprawl before entering the Greater Toronto Area's outer ring. The landscape remains predominantly low-lying throughout this drive, with only modest elevation changes as you move eastward. As you approach London and then continue through the Dundas area, you'll notice the terrain remains gently rolling at best, characteristic of southwestern Ontario's agricultural heartland. The most significant geographic feature you'll encounter is the Niagara Escarpment's influence as you draw closer to the Greater Toronto Area, though the highway routing means you won't experience dramatic elevation shifts.

Your drive takes you through several notable communities, including London and Woodstock, before the landscape becomes increasingly urbanized as you approach the sprawling Toronto metropolitan area. The final stretch toward Mississauga involves navigating through the busiest sections of Highway 401, where you should expect congestion during morning and evening rush hours. The QEW portion as you curve around the western edge of Toronto offers glimpses of the industrial waterfront and urban development that define this economic corridor.

For the most pleasant driving experience, plan your journey during spring or fall when weather conditions are typically mild and visibility is excellent. Winter driving along this route demands extra caution due to potential icing and reduced visibility, while summer traffic volumes can be substantial. Early morning departures help you avoid the heaviest congestion and give you a more relaxed, enjoyable experience on this important Ontario thoroughfare.
