British Columbia Highway 5 — the Coquihalla Highway — has a reputation among commercial drivers that is earned every winter. The 315-kilometre corridor from Hope to Kamloops climbs to 1,244 metres (4,081 feet) at the Coquihalla Summit, receives some of the heaviest snowfall of any highway in Canada, and closes multiple times each winter for avalanche control or storm-related hazards.

It is also the most important freight artery between the Port of Vancouver and the BC Interior. When the Coquihalla shuts down, the supply chain for much of western Canada feels it.

The Yellowhead Highway (Highway 16) stretches from Portage la Prairie, Manitoba to Prince Rupert, British Columbia — over 3,000 kilometres of Canada’s northern transcontinental corridor. For much of its length, the Yellowhead is a serviceable two-lane highway through boreal forest and prairie. But two sections in the mountain west require specific attention from commercial drivers: the Jasper–Hinton corridor in Alberta, and the McBride–Tête Jaune Cache section in British Columbia.

These stretches are dangerous for overlapping but distinct reasons: extreme wildlife density, remote location, severe winter weather, mountain terrain, and in the case of the BC section, a troubling history of violence against highway users that has given this road a dark nickname.

There are dangerous roads, and then there is Alberta Highway 63.

For decades, the 465-kilometre corridor between Edmonton and Fort McMurray carried a grim distinction: one of the highest per-kilometre fatality rates of any Canadian highway. The road became so notorious that provincial politicians, safety advocates, and the families of accident victims campaigned for years under the banner of “Twinning 63” — arguing that the single-lane highway was a preventable killer.

The Trans-Canada Highway is the longest national highway in the world, stretching over 7,800 kilometres from Victoria, BC to St. John’s, NL. For most of its length it is a manageable, if sometimes remote, route. But two sections in the western mountains stand apart: Rogers Pass through Glacier National Park in British Columbia, and the Banff–Lake Louise corridor on the BC–Alberta border through Banff National Park. Together, these segments represent some of the most consequential driving in Canadian commercial trucking.

Northern Ontario covers a staggering 800,000 square kilometres. Most of it has no roads at all. The communities that exist in this vast boreal zone — Hearst, Kapuskasing, Cochrane, Timmins — are connected by a handful of provincial highways that traverse some of the emptiest terrain in eastern North America. Among these, Highway 11 is the primary corridor, and the section between Hearst and Kapuskasing — roughly 100 kilometres of two-lane highway through the Clay Belt — represents the corridor at its most exposed.

The Queen Elizabeth Way — the QEW — is the primary expressway connecting Toronto, the western Greater Toronto Area, Hamilton, and the Niagara region. It is one of the busiest commercial vehicle corridors in Ontario, carrying massive freight volumes between Toronto’s distribution infrastructure and the US border at Niagara Falls and Fort Erie. Somewhere near the middle of this corridor, between the cities of Burlington and Hamilton, sits a structure that concentrates the QEW’s inherent dangers into their most intense form: the Burlington Skyway.

Northwestern Ontario is one of the most sparsely populated regions in Canada. The vast boreal forest between the Manitoba border and Thunder Bay is crossed by a thin ribbon of highway — Highway 17, the main surface route through the region and part of the Trans-Canada Highway system. The approximately 200-kilometre section between Kenora and Dryden distills everything that makes northern Ontario highway driving difficult: long distances, no services, dense wildlife, severe winters, and the particular hazard of fatigue that sets in when hours pass with no town, no fuel stop, and no change in scenery.

Highway 401 through southern Ontario is, by vehicle count, the busiest highway in North America — and arguably the world. At its widest point through Toronto, the 401 carries over 400,000 vehicles per day across up to 18 lanes of traffic. For commercial truck drivers, this corridor is the backbone of Canadian freight: virtually all goods moving between Windsor (and the US border at Detroit), Toronto, Montreal, and the Maritime provinces travel this route.
