Project Features

  • The three-kilometre rail line will branch off from Weston Subdivision (GO Georgetown corridor) and connect to Toronto Pearson with a new passenger station at Terminal 1.
  • The ARL will provide an express, frequent, shuttle-type service.
  • Self-propelled passenger rail vehicles powered by small, efficient diesel engines will be operated on the line.
  • These vehicles accelerate and decelerate quickly, making them suited to frequent, fast service.

Community and Green Benefits

  • For the first time, an express rail service will be available between Union Station downtown and Toronto Pearson International Airport.
  • Travellers will have quicker, easier, more reliable transportation between Toronto Pearson and downtown.
  • An estimated 1.2 million car trips will be eliminated in the first year of operation, reducing traffic congestion and air pollution.
  • Once air-rail service begins, trains will depart from Union Station and Toronto Pearson every 15 minutes.

Economic Benefits

  • Job creation in design and construction industries will stimulate economic growth for businesses and communities in the Greater Toronto and Hamilton Area (GTHA).
