Island Airport Expansion Plan Faces Traffic and Environmental Pushback

Ontario's ambitious plan to expand Billy Bishop Toronto City Airport has hit immediate resistance from the city's own waterfront experts, who say the project will gridlock traffic, clog transit, and harm the harbour.

At a legislative committee hearing, Toronto's waterfront secretariat presented stark warnings about the province's expansion proposal, which would allow jets to land and take off from the island airport and accommodate up to 10 million passengers annually—a fivefold increase from the current two million.

The secretariat's concerns are structural: the island and its access routes cannot absorb that volume without severe degradation. Traffic congestion on the Gardiner Expressway and Lake Shore Boulevard would worsen significantly. Transit ridership would spike beyond current capacity. Water quality in Toronto Harbour could suffer from increased traffic and infrastructure development.

Yet the province is moving forward without what many consider basic due diligence. A CBC News investigation found that the Ontario government has touted an $8.5 billion annual economic benefit by 2050—a figure the Toronto Port Authority says it's still studying. No complete economic analysis exists. No environmental assessment has been completed. No health impact study has been conducted.

Toronto Mayor Olivia Chow has called the move a "land grab" that bypasses public consultation. Transportation Minister Prabmeet Sarkaria frames it as a "nation-building project" essential to the economy. But without the studies, without the data, the city is being asked to accept massive infrastructure consequences on faith alone. That gap between the province's ambition and its evidence is what's fueling the pushback.
