How Toronto Got Addicted to Cars

Toronto’s car addiction didn’t happen by accident—it was engineered through postwar freeway building, transit choices that prioritized motorists, and later political decisions that locked in suburban, low-density land use. The result is a city where the 401 carries the heaviest traffic in North America and where daily life is shaped by driving, even though Toronto once had a streetcar-based, walkable urban form.

The story starts with a city built for rail. Toronto grew along streetcar lines after streetcar service began in 1861, and its early transit infrastructure—like the first train station opening in 1858 and the later Union Station transition in 1927—supported dense, connected neighborhoods. That changed after the 1940s, when suburban development accelerated across North America and Toronto followed the same playbook: freeways designed for cars, subsidies and incentives for automobile ownership, and the removal of streetcar capacity to make room for motor traffic. Streetcar lines were torn out despite resistance, including a Parliament Street line removed in 1966 and a Mount Pleasant streetcar line where a 1976 business association poll found 88% of respondents wanted to keep it.

Transit expansion reinforced the same priorities. The Toronto subway opened in 1954 with explicit language about eliminating streetcar operations in downtown to free main streets for one-way traffic. Later reporting framed the subway as a congestion-relief project for the central city—again, tied to road space for drivers rather than transit riders. Even regional GO train service was structured around the reality that riders had to drive to stations, not rely on walkable access.

Freeways accelerated the shift. Neighborhoods were bulldozed for the Gardner Expressway, and the Don Valley Parkway’s route avoided some demolition largely because Hurricane Hazel struck in 1954. Major public protest slowed further damage, with Jane Jacobs playing a prominent role in stopping the Spadina Expressway, warning that planners were clinging to outdated technology and treating neighborhoods as “hardware.” Yet the damage was already done: Toronto’s former streetcar-connected urban fabric had been replaced in many areas by office blocks and surface parking, while postwar suburbs persisted as a “yellow belt” of single-family housing.

Politics then amplified the car-centric pattern. In 1998, Ontario’s conservative government forced the amalgamation of Toronto with surrounding municipalities despite referendums in all six areas voting to remain independent. The move was widely speculated to be political—shifting influence toward a fast-growing, largely left-leaning Toronto while absorbing conservative suburban voting power. That suburban dominance shaped city council outcomes, including the election of Rob Ford, who tore up bike lanes, canceled transit projects, and governed without consistent council approval. After Ford, details emerged about “unfinanced capital,” effectively undisclosed debt, underscoring how governance choices can compound long-term costs.

The core takeaway is that Toronto’s transit and land-use trajectory is inseparable from municipal politics. Car-first planning became self-reinforcing: low-density suburbs reduced transit viability, transit underinvestment increased car dependence, and electoral outcomes kept the system in place. Still, the city’s future may hinge on new transit projects nearing completion—an opening to reverse decades of car-centric planning and recover lost urban potential.
