The short version

Air Canada plans to end five Canada–U.S. routes in 2027: Montreal–Seattle, Vancouver–Nashville, Vancouver–Raleigh-Durham, Toronto Billy Bishop–Boston, and Toronto Pearson–Charleston ¹.
The airline’s Toronto Pearson–Charleston service is its only direct route between Canada and South Carolina ¹.
Reports cite weaker demand as the reason for the cuts, but do not give detailed passenger figures for each route ¹².
The available sources do not state exact final flight dates or confirm replacement services, so travelers need to check their specific itinerary and current schedules.

Which trips will be affected by the 2027 changes?

The planned changes affect five city pairs: Montreal to Seattle, Vancouver to Nashville, Vancouver to Raleigh-Durham, Toronto Billy Bishop Airport to Boston, and Toronto Pearson Airport to Charleston ¹. The report says the cancellations begin in 2027, but it does not provide a final operating date for each route ¹.

The Charleston service is notable for travelers going to South Carolina: it is Air Canada’s only direct flight between Canada and that state ¹.

Why is Air Canada changing its schedule?

The reports link the cuts to weaker demand for cross-border travel ¹². One report says airlines have been trimming routes to smaller cities when they do not attract enough passengers ². The sources do not provide route-by-route passenger totals or a detailed explanation from Air Canada for each decision.

The travel figures in the reports use different comparisons. One says Canadian trips to the United States rose from the previous year in September, while remaining below 2024 levels ¹. Another reports that September 2026 trips were lower than in September 2024 ². Those figures offer context, but they do not establish why any particular traveler chose not to fly.

Are any other Air Canada U.S. routes changing?

A separate report says Montreal–Minneapolis, Montreal–Detroit, and Toronto–Indianapolis were already scheduled to be phased out by the end of October 2026 ². These are distinct from the five routes reported as ending in 2027 ¹².

The supplied reports are not a complete, continuously updated list of Air Canada schedule changes. Check the airline’s schedule for the dates and cities you plan to travel.

What can you do if your itinerary is affected?

The available reports do not confirm which alternative flights Air Canada will offer, whether other airlines will operate convenient options, or how individual bookings will be handled. They also do not say whether the airline will add new routes to replace the ones ending.

If you already have a ticket, check your booking and any messages from the airline or booking provider. If you have not booked, compare schedules for your travel dates, including itineraries with a connection, and confirm the details with the airline before making plans.

When will the last flights operate?

The reports say the five routes will be cancelled beginning in 2027, without listing the final flight date for each one ¹. The Charleston service has been described as seasonal; one report says it previously operated from March until the start of September ². That past pattern does not establish the route’s final dates in 2027.

Because schedules can vary by date, travelers should not assume that all five routes end at the same time. Confirm availability for the exact day you intend to travel.
