The proposed expansion of Billy Bishop Toronto City Airport is drawing fresh political and public attention after Toronto Port Authority CEO RJ Steenstra said the project could cost between $4 billion and $5 billion over a period of about 25 years. The estimate has intensified debate over the future of Toronto’s island airport, including questions about funding, jets, waterfront land, noise, traffic and the role of the City of Toronto in airport decisions.
The Billy Bishop Airport expansion cost is now one of the central issues in a broader fight over how Toronto and Ontario should plan for future air travel demand. Supporters say the airport must modernize to serve a growing province, reduce pressure on Toronto Pearson and create new economic opportunities. Critics argue that a multi-billion-dollar expansion needs a clear business case, stronger public consultation and serious review of environmental and neighbourhood impacts.
Billy Bishop Airport Expansion Cost Could Reach $5 Billion
Steenstra told a Queen’s Park committee that the expansion would not be an overnight project, but a phased investment designed to meet future demand. The proposed cost range of $4 billion to $5 billion would cover a long-term buildout rather than a single immediate construction phase.
He also said there would be little, if any, public money involved, although the federal government has not yet clearly stated whether taxpayer dollars could be part of the plan. Commercial airports in Canada are generally self-funded through users, airlines and airport-related revenues, and Steenstra said Billy Bishop would follow that model.
Still, the size of the estimate has raised major questions. A $5-billion price tag is significant for any public-facing infrastructure project, especially one located on Toronto’s waterfront, where land use, parks, housing, transportation and environmental concerns are already politically sensitive.
Expansion Plan Tied to Provincial Legislation
The debate comes as Ontario advances the Building Billy Bishop Airport Act, 2026. If passed, the legislation would allow the province to take over the City of Toronto’s role in the tripartite agreement that governs the airport. The bill would also allow certain city-owned lands connected to the airport to vest in the Crown, with compensation to the city based on market value.
The Ontario government says the legislation is meant to support the long-term modernization and expansion of Billy Bishop Airport. The province argues that a larger airport could help meet future demand in southern Ontario, reduce pressure on Pearson, increase competition in air travel and support jobs in aviation, tourism and construction.
Billy Bishop currently serves roughly 2 million passengers per year and connects Toronto to more than 20 cities in Canada and the United States, according to the province.
Jets and Runway Expansion Remain Controversial
One of the biggest issues is whether expansion would allow jets to operate from Billy Bishop. Premier Doug Ford and provincial Transportation Minister Prabmeet Sarkaria have supported expanding the airport to allow jet service, while opponents have raised concerns about noise, waterfront disruption, climate impacts and pressure on nearby neighbourhoods.
The idea of jets at Billy Bishop is not new. It has been debated for years, and previous proposals sparked intense public reaction. The current plan has revived many of those same concerns, especially because the airport sits close to residential areas, parks, the waterfront and downtown Toronto.
Supporters see jets as a way to increase routes, improve convenience and make Toronto more competitive. Critics see them as a threat to quality of life, waterfront planning and public space.
Critics Question the Business Case
Opposition politicians have criticized the Ford government for not clearly presenting a business case for the expansion. During a Queen’s Park committee hearing, NDP MPP Chris Glover challenged Transportation Minister Prabmeet Sarkaria over the government’s claim that the expansion could generate major economic benefits. Glover argued that the province had not shown enough cost-benefit analysis to justify moving forward.
That criticism is likely to grow now that the estimated cost has reached as high as $5 billion. For many residents, the central question is simple: who pays, who benefits and what does Toronto lose in return?
If the expansion is funded mainly through airport revenues, airlines and passengers, supporters may argue that taxpayers are protected. But if any level of government eventually contributes funding, the public debate could become sharper.
City of Toronto Pushback Adds Political Tension
Toronto Mayor Olivia Chow has opposed the province’s move, calling it a power grab and land grab. The province has said some lands are being listed for due diligence and that not all identified parcels may necessarily be needed. The disagreement has added a strong city-versus-province dimension to the airport debate.
This matters because Billy Bishop is not just an airport. It is part of Toronto’s waterfront, a space shaped by competing priorities: transportation, parks, housing, tourism, business, recreation and environmental protection. Any major airport expansion would affect more than air passengers.
Supporters Say Expansion Could Boost Travel and Jobs
Supporters of the project argue that Toronto needs more airport capacity as Ontario’s population grows. The province says expanding Billy Bishop could improve connectivity, support business travel, strengthen tourism and create thousands of jobs.
There is also an argument that a stronger downtown airport could reduce pressure on Pearson and give travellers more options. For business passengers and short-haul travellers, Billy Bishop’s downtown location is one of its biggest advantages.
However, those potential benefits must be weighed against the cost, the complexity of building around water, and the impact on surrounding communities.
Public Trust Will Depend on Transparency
The future of the airport expansion will likely depend on how clearly officials explain the plan. Residents will want more details about construction phases, environmental assessments, passenger projections, runway changes, jet operations, funding sources and impacts on waterfront land.
Without transparency, the Billy Bishop Airport expansion cost could become a symbol of rushed planning. With strong public evidence and open consultation, supporters may have a better chance of convincing residents that the project is worth the investment.
