Air Canada and United Airlines are expanding their Canada-U.S. summer 2027 routes to increase non-stop access and connection options for travelers. The expansion follows an agreement to renew and widen their Transborder Joint Business Agreement, subject to regulatory approval.

New Air Canada flight paths

Air Canada will introduce several new services to broaden its U.S. network. These specific additions include:

  • Toronto to Louisville, with daily service beginning in May
  • Montréal to Indianapolis
  • Edmonton to Newark

Additionally, the airline plans to increase capacity on its Edmonton to San Francisco route by utilizing the larger Airbus A220 aircraft.

How will United Airlines expand its service?

United Airlines is also introducing new seasonal and expanded flights to bolster transborder connectivity. The airline's plans include launching seasonal service from its Newark hub to St. John's, Newfoundland.

From Denver, United will add new service to both Ottawa and Québec City. The carrier also intends to increase the number of flights between Washington, D.C., and Québec City, while raising daily seats between Denver and Winnipeg by 65 per cent.

Impact of the transborder partnership

The expansion is part of a long-standing partnership that has seen 20 new routes created between Canada and the U.S. since 2022. More than 4.3 million passengers have flown jointly on United and Air Canada through this arrangement.

For Canadian travelers, the partnership supports connectivity across more than 50 communities. It brings approximately two million customers connecting to or from the U.S. onto Air Canada’s domestic network each year. Beyond major hubs, the agreement enables direct transborder services from cities including Calgary, Edmonton, Halifax, Ottawa, Québec City, Regina, St. John’s, and Winnipeg.

Strengthening Canada-U.S. connectivity

The partnership aims to support both leisure and business travel. The expanded network is designed to connect Canadian communities to major U.S. hubs, providing travelers with more departure options and integrated through-fares. This coordination is intended to help passenger networks remain resilient during travel disruptions.
