About Ontario's Highway Network
Ontario's highway system is one of the most extensive in North America, featuring the famous 400-series highways that connect major cities across the province. Highway 401, running through Toronto, is the busiest highway in North America, with sections carrying over 500,000 vehicles daily. The network includes controlled-access freeways, provincial highways, and regional roads that facilitate commerce, tourism, and daily commuting across Ontario's vast geography.
The 400-series highways form the backbone of Ontario's transportation infrastructure. Highway 401 stretches 828 kilometers from Windsor to the Quebec border, connecting Windsor, London, Toronto, Kingston, and beyond. Highway 400 runs north from Toronto to Sudbury, serving as the primary route to cottage country and Northern Ontario. Highway 417 (the Queensway) connects Ottawa to the 401 near the Quebec border, serving as the capital region's main expressway.
