Ontario Highway Map
Focus on major highways and 400-series routes.
Ontario's Complete Road Network
Ontario's road network is one of the most extensive in North America, connecting every community from Windsor to Kenora and from Niagara Falls to the northern shores of Hudson Bay. The network includes 400-series controlled-access highways, numbered provincial highways, county and regional roads, and thousands of kilometers of local streets and rural routes. This comprehensive road system supports Ontario's economy, facilitates tourism, enables commerce, and connects communities across the province's vast geography.
The road classification system includes several levels. 400-series highways are limited-access freeways with numbered exits, designed for high-speed travel between major centers. Provincial highways (numbered 2 through 175) range from multi-lane divided highways to two-lane rural routes. County roads and regional roads provide local connections within specific administrative areas. Township roads and concession roads follow Ontario's historic survey grid, particularly in rural Southern Ontario. Northern Ontario features resource roads and logging routes that access remote areas.

Road Classifications and Uses
400-series highways form the backbone of Ontario's transportation network, handling the majority of long-distance traffic. These include Highway 401 (Canada's busiest highway), Highway 400 (Toronto to Northern Ontario), and Highway 417 (Ottawa's expressway). King's Highways are provincial routes numbered 2-175, maintained by the Ministry of Transportation. Historic routes like Highway 2 (the original Toronto-to-Montreal route) and Highway 7 (Trans-Canada Highway through Southern Ontario) carry significant regional traffic. County and regional roads connect smaller communities and provide access to rural areas, numbered separately by each county. Resource roads in Northern Ontario access mining sites, forestry operations, and remote communities, often unpaved and maintained to industrial standards rather than public highway standards.
