Air Canada is redrawing part of its U.S. network after another year in which cross-border travel failed to fully recover to earlier levels. The carrier has removed five Canada–U.S. routes from its upcoming schedules, including a relatively new downtown Toronto–Boston connection and its only service to Charleston, South Carolina. The changes arrive as Statistics Canada’s preliminary September data show Canadian-resident return trips from the United States by air climbed 11.6% from a year earlier but remained 18.7% below September 2024. Air Canada has characterized the route changes as commercial decisions made while aligning capacity with demand and travel patterns. Importantly, the airline is not abandoning U.S. expansion: three new American routes are planned for summer 2027, making the latest moves more of a network reshuffle than a wholesale retreat.
Toronto Billy Bishop–Boston: A New Route Lasts Only Months
Perhaps the most striking cut is Air Canada’s service between Billy Bishop Toronto City Airport and Boston Logan International Airport. The route only began on July 1, 2026, as part of what Air Canada had described as its most significant expansion at Toronto’s island airport in 35 years. Boston was initially offered three times a day using 78-seat De Havilland Dash 8-400 aircraft operated by Jazz Aviation under the Air Canada Express brand. Its arrival followed the introduction of U.S. customs pre-clearance at Billy Bishop and was designed in large part around the convenience of business travellers able to leave from downtown Toronto rather than make the trip to Pearson. Less than half a year later, however, the service is scheduled to disappear beginning in December 2026.
The short lifespan makes Boston an unusually visible example of how quickly airlines can reconsider a new market when conditions change. Air Canada has not released route-specific passenger totals, load factors or profitability figures showing precisely why Billy Bishop–Boston did not make the cut. The broader environment provides context rather than a complete explanation: Canadian air trips returning from the United States were still 18.7% below their September 2024 level despite improving from 2025. Boston itself is not disappearing from Air Canada’s network. Travellers can still reach the city nonstop from Toronto Pearson, Montréal and Halifax. The other U.S. destinations introduced from Billy Bishop—New York LaGuardia, Chicago O’Hare and Washington Dulles—were also not included among the five newly removed routes. What disappears is the particularly convenient downtown Toronto option, only months after Air Canada made it one of the centrepieces of its island-airport expansion.
Toronto Pearson–Charleston: Air Canada Leaves a South Carolina Market
The Toronto Pearson–Charleston route has travelled a very different path. Air Canada launched the service on March 28, 2024, initially promoting it as a daily connection and a significant new link between Canada and South Carolina. Charleston International Airport described it at the time as South Carolina’s only daily nonstop international flight. During the route’s first season, more than 20,000 passengers travelled on roughly 400 flights through October 2024, according to figures later provided by the airline, with an Air Canada network-planning executive describing the first season as solid. But the schedule subsequently became more limited. Industry schedule analysis cited by PAX shows Toronto–Charleston departures declined from about 200 in 2024 to just 92 in 2026. Air Canada had previously been expected to bring the service back in April 2027; that return has now been removed.
Charleston therefore stands apart from the other four cuts because Air Canada will no longer serve the destination from another Canadian gateway. The decision also comes against a difficult tourism backdrop for parts of South Carolina. University of Toronto School of Cities research using mobile-device activity found Canadian visits to Myrtle Beach fell by roughly 65% year over year during the period studied. Myrtle Beach and Charleston are separate tourism markets, so the finding should not be treated as evidence of demand on the Toronto–Charleston flight itself. It does, however, illustrate how sharply Canadian travel patterns changed in some traditionally popular southern U.S. destinations. Air Canada had already shortened Charleston’s 2026 flying season as surging jet-fuel costs prompted schedule reductions. For travellers from Ontario heading to the South Carolina Lowcountry, the latest decision now means giving up the direct Air Canada option altogether and relying on connecting itineraries or alternative carriers.
Vancouver–Nashville: A Western Canada Experiment Is Shelved
Air Canada’s nonstop between Vancouver and Nashville was considerably newer. It launched in May 2025 as part of a broader expansion of the airline’s Vancouver transborder network, with seasonal service operating several times a week using Boeing 737 MAX aircraft. Nashville International Airport promoted the new flight not only as a connection to British Columbia, but also as a potential gateway for Tennessee travellers heading through Vancouver to destinations in Japan and South Korea. That connecting strategy reflected Vancouver International Airport’s importance to Air Canada as a Pacific hub. The Nashville route was eventually scheduled for as many as four weekly frequencies during peak periods, creating a rare nonstop link between western Canada and one of the fastest-growing tourism and entertainment destinations in the American South. Plans had called for the service to return again in May 2027.
That planned return is now gone. For passengers in Vancouver, the practical loss is a nonstop rather than the U.S. city itself disappearing from Air Canada’s network. The carrier continues to serve Nashville through its eastern Canadian gateways, including Toronto and Montréal. Air Canada has also not published specific load factors or profitability numbers for Vancouver–Nashville, making it difficult to say whether weak route-level demand, operating economics or a combination of factors ultimately determined its fate. That distinction matters because the airline is simultaneously expanding elsewhere in the United States. For summer 2027, it plans to add Toronto–Louisville, Montréal–Indianapolis and Edmonton–Newark service. In other words, aircraft and capacity are not simply being pulled out of the transborder market. They are being moved among city pairs. Vancouver–Nashville appears to be one of the relatively young routes that failed to retain a place as Air Canada reassessed where its U.S. flying could generate the strongest returns.
Vancouver–Raleigh-Durham: The Warning Signs Appeared Before the Cut
The Vancouver–Raleigh-Durham route offers some of the clearest evidence that Air Canada was already reducing exposure before removing the service from 2027 schedules. The seasonal nonstop launched on June 4, 2025, operating three times weekly and giving Raleigh-Durham its first nonstop link to Vancouver. Air Canada originally positioned the flight as part of a major expansion from its western hub, offering North Carolina travellers not only direct access to British Columbia but also potential connections across Air Canada’s Pacific network. The service did not maintain its original footprint for long. In 2026, Air Canada ended the seasonal operation roughly two months earlier than initially expected. Schedule data cited by industry reports show departures declined 27% compared with 2025, while the number of available seats dropped 34%. The airline subsequently decided not to bring the route back for summer 2027.
Passenger performance helps explain why the route attracted scrutiny, although Air Canada has not publicly identified one single metric as the reason for its decision. U.S. Department of Transportation data cited in industry analysis put the route’s load factor at 66.4% in 2025 and 69.6% in 2026, with July 2026 reaching about 76%. That improvement was not enough to preserve the Vancouver nonstop. Raleigh-Durham will nevertheless remain connected to Air Canada through Toronto and Montréal, so the carrier is not exiting the North Carolina market. Local reporting also notes that RDU has experienced another Canadian pullback: WestJet dropped its seasonal Calgary service after pointing to a significant decline in transborder demand. Losing Vancouver reduces RDU’s roster of nonstop international destinations, while western Canadian passengers face an extra connection. Compared with some of the other cuts, this route shows the clearest progression from reduced flying, to a shortened season, and finally to removal from the next year’s schedule.
Montréal–Seattle: A Comeback Is Cancelled Before It Happens
Montréal–Seattle has experienced an especially stop-start history. Air Canada operated the route in 2025 and had initially scheduled another seasonal run for 2026, including service with the Airbus A220. That plan was removed before the 2026 summer season. By June, aviation-industry reporting indicated the nonstop would instead return in May 2027, creating a direct connection once again between Montréal and the Pacific Northwest. Only a few months later, that comeback has also disappeared from the schedule. The loss leaves Montréal travellers without Air Canada’s nonstop to Seattle, although the carrier will continue serving Seattle from Vancouver and Toronto. Passengers originating in Montréal can therefore still reach the city within the Air Canada network, but with a connection where the direct service had been expected to return.
The repeated schedule revisions underscore why the five cancellations should not be read as a simple story of Canadians suddenly abandoning U.S. air travel altogether. September 2026 actually produced the sixth consecutive year-over-year increase in total Canadian-resident return trips from the United States by air and automobile, reaching about 1.89 million. Air trips alone rose 11.6% from September 2025. The problem is the comparison with the stronger 2024 market: air travel remained 18.7% lower. Airlines plan networks on individual route economics rather than national percentages, and Air Canada is continuing to invest south of the border where it sees opportunity. Its summer 2027 additions include Louisville, Indianapolis and Newark, while an expanded partnership with United Airlines is intended to provide more connecting options between the two countries. The picture emerging is therefore one of selective rebuilding: Canadians are gradually flying south again, but not yet in the same numbers—or necessarily to the same places—as they did two years earlier.
