Air Canada and United Airlines are expanding Canada-U.S. connectivity for summer 2027, with new routes from Toronto, Montréal, Edmonton, Newark and Denver. The carriers also agreed on Oct. 16 to renew and expand their Transborder Joint Business Agreement, subject to Canadian regulatory approval.
New Routes Across the Border
Air Canada will launch flights from Toronto to Louisville from Apr. 28, 2027, increasing to daily service in May. Montréal to Indianapolis and Edmonton to Newark will follow on Jun. 1, with the Montréal service operating daily and Edmonton service four times weekly. Air Canada will also add capacity between Edmonton and San Francisco by deploying the larger Airbus A220.
United Airlines will introduce seasonal Newark to St. John’s service and add new flights from Denver to Ottawa and Québec City. It will also increase flights between Washington, D.C., and Québec City and boost daily seats between Denver and Winnipeg by 65%. St. John’s International Airport (YYT) Chief Executive Dennis Hogan said the Newark route reconnects the city with Newark for the first time in more than a decade.
Stéphane Poirier, President and CEO of Québec City Jean Lesage International Airport (YQB), said:
“Today’s announcements are a game changer for Québec City. A new direct link to Denver, year-round service to Chicago, and five weekly flights to Washington Dulles are exactly the kind of connections our tourism industry and business community need to thrive.”
United Grows in Canada as the Partnership Renews
The new routes build on the airlines’ Transborder Joint Business Agreement, which began in 2022. Since then, it has created 20 new routes, including six added in 2026, and carried more than 4.3 million passengers on both carriers. The airlines serve 10 Canadian gateways and offer more than 1,200 connecting itineraries. To facilitate the renewal, Air Canada has applied to Transport Canada for approve of the updated agreement.
Air Canada Executive Vice President and Chief Commercial Officer Mark Galardo said the airline is “giving customers more ways to travel directly to U.S. destinations,” with connections across United’s network. Air Canada said the routes support business and leisure travel and its strategy of connecting U.S. passengers through its Canadian hubs to Europe and Asia.
