The Trans-Canadian Highway was originally designed to allow Canada’s small towns and rural areas to transport their goods, people and goods, but it became a major transportation network as the country expanded westward in the 19th century.

More than 100 million vehicles passed through its lanes during its 100-year history, connecting more than 1.2 million residents to destinations in Canada.

It was the highway that connected Vancouver with Montreal, Montreal to Ottawa, Ottawa to Toronto and Toronto to Halifax.

The highway also became the transport network for the largest city in North America, which became Canada’s first and largest urban centre, with more than 2.3 million people, about one-third of the population.

With more than 11 million kilometres (531,000 miles) of highway built and maintained, the Transcontinental Railway became the world’s busiest railroad.

Transportation became the major drawcard of the new, larger cities, which expanded rapidly after the war and in the 1950s and 1960s.

Today, more than a third of Canada’s population lives in a metropolitan area.
