Ontario Trans-Canada Highway Main Route (#17)
Why is there no Highway 1 in Ontario?
Ontario is using the “400” series of highways to designate highways with 4-lanes (or more) divided highways with limited access. The Macdonald-Cartier Freeway from Windsor to Toronto to Montreal was designated Highway 401 (it never existed previously as a Highway 1, though the road connecting towns along Lake Ontario that it superceded in importance was designated Highway 2. And Highway 400 was the Highway from Toronto to Barrie and continue on into cottage country.
As roads are upgraded, they may become “400” Highways. Like, Highway 10 turning into 410 near Toronto and Highway 17 turning into 417 between Ottawa and the Quebec border (and since, extended west to Arnprior and Renfrew)
Highway 17 Route Overview
Here is the route of the Trans-Canada Highway from east to west:
After crossing from Quebec, the highway winds up the fertile and wide Ottawa Valley until it reaches Ottawa, Canada’s capital. The highway from the Quebec border to Arnprior, just west of Ottawa is designated “highway 417” and is a divided highway, and in Ottawa it is also called the “Queensway”. Bicyclists must use Route 17 which is a 2-lane road which runs along the Ottawa River from Kanata to the Quebec border.
Ottawa was originally called “Bytown,” and located where the Ottawa River is joined by the Rideau and the Gatineau rivers, the city has many stone buildings dating back before Confederation (1867). Ottawa is the endpoint of the Rideau Canal, which was built by Colonel By (hence the city’s original name) which was built to provide access to Lake Ontario and Kingston for the British Navy away from US view along the St Lawrence. Today, the Rideau Canal is a mecca for small boaters.
