Public consultation launched: Transport Canada began reviewing the proposed Air Canada–United Airlines joint-venture update on October 16, 2026.
Existing agreement dates to 2022: The partnership allows coordination of schedules, pricing, marketing, sales and revenue management on eligible routes.
Additional routes proposed: Ten listed markets, including Montréal–Chicago, Ottawa–New York and Vancouver–San Francisco, are currently excluded from the arrangement.
Competition under scrutiny: Regulators will assess consumer impacts, economic benefits and potential effects on airline competition.
Separate network expansion: Both airlines have announced additional summer 2027 routes, distinct from the proposed agreement update.
November 15 deadline: Canadians and industry stakeholders can submit feedback before the consultation closes.
Proposed changes would bring additional Canada–U.S. routes under the airlines’ cooperation agreement, raising questions about connectivity, competition and passenger benefits.
Transport Canada has launched a public consultation on a proposed expansion of the joint business arrangement between Air Canada and United Airlines, inviting travellers, industry stakeholders and other interested parties to provide feedback on the potential impact of the changes.
The proposal would add Canada–United States routes that are currently excluded from the airlines’ existing agreement, allowing the two carriers to coordinate their operations across a broader portion of the transborder market. The government’s review will consider whether the proposed changes are in the public interest, including their potential effects on airline competition, connectivity and travellers.
The consultation, announced on October 16, 2026, is scheduled to remain open until November 15, 2026. The proposal has not yet received final approval.
Air Canada and United Airlines have maintained a close commercial relationship for years through their membership in Star Alliance and a transborder joint business arrangement.
The arrangement allows the airlines to coordinate certain aspects of their Canada–U.S. services, including schedules, pricing, sales and revenue management on eligible routes. The objective is to offer more convenient connections and a more integrated travel experience for passengers travelling between the two countries.
The proposed update would extend this cooperation to routes that currently fall outside the agreement. If approved, the expansion could give both airlines greater flexibility to coordinate schedules and connect passengers across their respective networks.
However, the scope of the proposed changes also makes regulatory scrutiny important, particularly where the airlines compete directly or where travellers have limited alternative services.
The proposed expansion covers several important transborder markets connecting Canadian cities with major U.S. destinations.
Routes identified as currently excluded from the arrangement include:
Montréal–Chicago
Montréal–Washington, D.C.
Ottawa–New York
Ottawa–Washington, D.C.
Toronto–Cleveland
Toronto–Denver
Toronto–Houston
Toronto–San Francisco
Toronto–Washington, D.C.
Vancouver–San Francisco
Calgary–Houston, a previously suspended route, has also been identified among the routes excluded under the existing arrangement.
Bringing additional routes within the joint business agreement could allow the airlines to align their schedules and commercial strategies more closely. The practical effect on each market, however, would depend on the final scope of the approved arrangement and the services operated by each carrier.
Transport Canada’s public-interest assessment provides an opportunity for passengers, consumer organisations, businesses, airports, competing airlines and other stakeholders to express their views on the proposed expansion.
The review will consider the potential benefits of closer airline cooperation alongside concerns about competition and consumer choice. Relevant issues include whether the agreement could improve connectivity, support economic activity and deliver a better travel experience, as well as whether it could weaken competition on affected routes.
Following the assessment, the government could approve the proposal, attach conditions or decline to authorize the changes.
The consultation deadline is November 15, 2026. Interested parties should refer to Transport Canada’s official consultation page for submission instructions and the latest information.
The proposed arrangement could offer passengers more coordinated schedules, easier connections and greater flexibility when travel plans change. However, closer coordination between competing airlines can also raise concerns about pricing and reduced independent competition on overlapping routes.
Transport Canada says its assessment will examine potential economic effects, the national transportation system and competition. Under the Canada Transportation Act, the minister can approve the proposal, approve it with conditions or refuse it.
The consultation is open to the travelling public, aviation industry representatives, consumer organisations, tourism groups, Indigenous communities and other interested stakeholders. Feedback can be submitted through the official Transport Canada consultation page or by email to TC.natair-aernat.TC@tc.gc.ca. The deadline is November 15, 2026.
The regulatory review coincides with a separate announcement by Air Canada and United Airlines detailing new transborder services for summer 2027. Air Canada plans to launch Toronto–Louisville, Montréal–Indianapolis and Edmonton–Newark flights, while United has announced additional services linking Canadian cities with U.S. destinations. These network changes are distinct from the proposed joint-venture amendment and remain subject to applicable approvals.
The proposed expansion represents another stage in the evolution of the airlines’ partnership, which has operated under its current joint business arrangement since 2022. For the airlines, a broader agreement could improve network coordination and strengthen connections across North America.
For passengers, the central question is whether those efficiencies will translate into better schedules, more convenient journeys and competitive fares. Transport Canada’s assessment will help determine whether the proposed benefits outweigh any potential harm to competition.
The outcome will be important for the future of Canada–U.S. aviation, particularly for travellers and businesses that depend on reliable cross-border connections. Until the government completes its review, however, the expanded arrangement remains a proposal rather than an approved change.
1. Three new Air Canada routes: Toronto–Louisville, Montréal–Indianapolis, and Edmonton–Newark will expand direct connectivity between Canada and the United States.
2. United Airlines adds new routes: Seasonal Newark–St. John’s service will return, while new Denver–Ottawa and Denver–Québec City routes strengthen connections to Canada.
3. Increased capacity: United will boost daily seat capacity between Denver and Winnipeg by 65% and increase flights between Washington, D.C., and Québec City.
4. Larger aircraft for Edmonton–San Francisco: Air Canada will deploy the Airbus A220 on the route to increase capacity.
5. Expanded airline partnership: Air Canada and United have agreed to renew and expand their Transborder Joint Business Agreement, subject to regulatory approval from Transport Canada.
6. More than 1,200 connecting itineraries: The partnership offers integrated ticketing, coordinated schedules, improved connections, and greater flexibility during travel disruptions.
7. 20 new transborder routes since 2022: The partnership has expanded its network, with more than 4.3 million passengers having flown jointly on the two airlines since its establishment.
8. Stronger regional connectivity: The expanded network aims to improve access to U.S. business hubs, support tourism and trade, and strengthen connections for communities across Canada.
9. Key launch dates: Toronto–Louisville service is scheduled to begin on April 28, 2027, while Montréal–Indianapolis and Edmonton–Newark services are scheduled to start on June 1, 2027.
10. Regulatory approval pending: The proposed renewal and expansion of the partnership requires government approval before the amended agreement can take effect.
