The Transcanadian Highway is the main East-West connection road within Canada. It is managed by the Provinces and the Federal, and runs through all the provincial capitals cities of the country and three metropoles starting from St. John's, NewFoundLand all the way to Victoria, British Columbia. Though, the highway network system in itself is managed by the provinces and the road is having a very different design depending of the province crossed.
Bear in mind that except in around the most densely populated area, most the Transcanadian Highway is a simple 2 lanes collector road for most of its distance (when it is called 'Route'). It is usually considered as a motorway where the denomination is starting with 'H' or 'A' such as in Quebec, Ontario and around Winnipeg for example.
Quebec Highway Network
Ontario Highway Network
In Ontario, the Transcanadian splits into a Northern, a Middle and a Southern branch which reverses in Thunder Bay. The Route 11 join the route 117 in Abitibi, Quebec aiming then South towards North Bay and the Route 17 Junction and North-West until Thunder Bay. From there it goes South to the Fort Frances Border Crossing to Minnesota.
The Middle branch starts at the Quebec border near Montreal as the H-417 heading towards Ottawa, continuing from there as the Route 17 towards Sault Ste.Marie (Border crossing to Michigan), following the Lake Superior to Thunder Bay and further to Manitoba.
The Southern branch, depart from Ottawa as the Route 7 in direction of Toronto and Oshawa. From there it heads Northbound as simultaneously the Route 12 around Lake Simcoe, the H-400 and route 69 until Sudbury where it merge with the Route 17.
British Columbia Highway Network
In British Columbia, the Transcanadian follows the same path than in the Prairies. The Route 1 (becoming the H-1 near Vancouver Area), quitting Banff National Park in Alberta heads South towards Vancouver, through Kamloops all the way until Victoria on Vancouver Islands where the Transcanadian also become shortly the H-19.
Maritimes Highway Network
In New Brunswick, the Transcanadian consists of the H-2 stretching from Quebec onto Nova Scotia and passing through Fredericton and Moncton. Just before the Nova Scotia border, the Route 16 branch head East to reach the Confederation Bridge to Prince Edward Island.
In Prince Edward Island, the Transcanadian becomes the Route 1 on the Confederation Bridge in direction of Charlottetown, the provincial capital, before continuing further South to Woods Island ferry crossing to Nova Scotia.
In Nova Scotia, the Route 104 stretches from the New Brunswick border further East, passing Truro (the junction to the Route 102 to Halifax), until Sydney for the ferry to the NewFoundLand. Near New Glasgow, the Route 106 branch of the Transcanadian reaches the coast near Pictou for the ferry to the Prince Edward Island.
In NewFoundLand, the Route 1 crosses the island as part of the Transcanadian from Channel-Port aux Basques where the ferry from Sydney, Nova Scotia arrives, all the way to St. John's the provincial capital.
Prairies and Alberta Highway Network
West of Winnipeg, after Portage la Prairie, the Transcanadian splits in two, the Route 1 continuing through Saskatchewan and Regina, Alberta (Calgary and Banff National Park) towards British Columbia.
