Entire Toronto transit line will shut down for the whole weekend

In case air travel wasn't already enough of a challenge right now, travellers relying on the UP Express will be forced to get to and from Toronto Pearson International Airport this weekend via buses.

Metrolinx has announced a full-line outage for the UP Express throughout the weekend of Saturday, Nov. 8 and Sunday, Nov. 9, 2025, due to ongoing construction.

Trains will not serve any of the four stations along the UP Express during the outage, and Metrolinx's plan to implement replacement buses may require commuters to tack on extra travel time when planning their trips.

Travel times could be as much as double between Union Station in downtown Toronto and Pearson International Airport straddling the Toronto-Mississauga boundary, with trips on the express rail line to be replaced by GO buses forced to weave through city traffic.

While the UP Express moves passengers between downtown and the airport in as little as 25 minutes, Metrolinx warns that replacement GO buses will cover the same distance in an estimated 30 to 50 minutes — meaning travel times could double for some trips.

The UP Express closure could coincide with a challenging period for air travel amid the ongoing U.S. government shutdown. The U.S. Federal Aviation Administration plans to cut flights at 40 airports across that country on Friday, which would impact many Canadian travellers.

The full-line UP Express outage is planned to conclude in time for the start of regular commuter service on Monday, Nov. 10.

In addition to Metrolinx's UP Express closure, the TTC has announced a full-weekend shutdown on Line 1 Yonge-University between St George and St Andrew stations, further complicating travel around the city in the coming days.
