Air Canada, United seek to update transborder joint venture; Transport Canada opens public interest review

Why it matters

Air Canada and United Airlines have formally notified Canada's Minister of Transport that they want to update their joint business arrangement for flights between Canada and the United States. In place since 2022, the deal allows the two carriers to coordinate flight schedules, ticket prices, marketing, sales and revenue management on certain Canada-U.S. routes — so any expansion directly affects transborder fares and competition.

On October 16, 2026, Transport Canada announced a formal public interest assessment of the proposal, examining its economic impacts for Canadians and its effects on competition. The department will consult airlines, consumer organizations and other stakeholders, and Canadians can submit comments through letstalktransportation.ca until November 15.

The final call rests with the Minister of Transport, who may authorize the joint venture, authorize it with conditions, or refuse it. Transport Minister Steve MacKinnon said a thorough public interest assessment ensures any expanded cooperation between the carriers benefits Canadians and drives economic growth, connectivity and jobs.

Alongside the filing, the airlines announced new routes: Air Canada will add Toronto–Louisville, Montréal–Indianapolis and Edmonton–Newark; United will launch seasonal Newark–St. John's service plus new Denver–Ottawa and Denver–Québec City flights, add Washington, D.C.–Québec City frequencies, and boost Denver–Winnipeg seat capacity by 65 per cent.

According to the airlines, the partnership has created 20 new transborder routes since 2022, carried more than 4.3 million passengers on joint itineraries, and enabled over 1,200 connecting itineraries with through fares. Testing those claims is the government's review's job.
