United Airlines has quietly trimmed its transborder network, cutting five nonstop routes between the United States and Canada amid soft demand that many attribute to the ongoing trade tensions between the two countries. Canadians have been favouring domestic trips and non-US destinations, and the numbers show it: cross-border flying is down across the industry, not just for United.
The axed routes span the country. From Washington Dulles, United ended seasonal service to Calgary — flown with Boeing 737-800s and MAX 8s, and with no other airline on the route — plus its Embraer E175 link to Halifax in the Canadian Maritimes. From Chicago O'Hare, the sole nonstop to Edmonton has disappeared, meaning travellers between the two cities now have to connect. Out west, Newark's nonstop to Vancouver was cut in October, though Air Canada and JetBlue still fly it. And from Los Angeles, United dropped its MAX 9 service to Toronto Pearson, leaving Air Canada and Porter Airlines to cover that city pair.
United hasn't retreated from Canada entirely — far from it. It remains the second-largest airline between the two countries, behind Air Canada but ahead of Delta, WestJet and Porter. Its busiest Canadian routes are Newark–Toronto with 47 weekly departures this November, followed by Chicago O'Hare–Toronto with 41. Newark–Quebec City, Dulles–Toronto and San Francisco–Vancouver each get 21 weekly flights, with 14-weekly frequencies from Washington to Ottawa, Montreal and Toronto, and from Chicago to Ottawa and Montreal. The close partnership with Air Canada also helps fill gaps where United has pulled out.
For travellers, the practical impact depends on where you're headed. Calgary, Halifax and Edmonton have each lost a US link entirely or seasonally, so you'll likely need a connection — or consider Air Canada or WestJet alternatives. On routes like Vancouver–New York or Toronto–Los Angeles, competition remains, so check Air Canada, JetBlue or Porter before defaulting to United. Expect fewer nonstop options and possibly higher fares on thinner transborder routes as airlines recalibrate to weaker demand.
