transit expansion Projects

Outdoor sidewalk

Congestion in the Greater Toronto and Hamilton Area (GTHA) is becoming a more serious problem as the region grows. The existing infrastructure is not serving all of the people currently traveling in and out of the GTHA and will not be able to support the projected future growth in the region. One part of moving toward improving this situation is a greater coordination and integration of all modes of transportation in the region.

Metrolinx supports a mission to champion and deliver mobility solutions for the GTHA through its operating divisions and transit initiative partnerships.

GO Transit

GO Transit is an operating division of Metrolinx. GO Transit is Canada’s first, and the Province of Ontario’s only, interregional public transportation service for the GTHA.

On May 14, 2009, GO Transit officially merged with Metrolinx. The merger maximizes the two organizations’ strategy and planning expertise and implementation and operations know-how to build rapid transit projects faster and improve customer service.

Union Station Revitalization

Union Station, Canada’s busiest transportation hub, is being transformed. When complete, it will have triple the interior space, a new PATH connection, and a second subway platform to provide better passenger circulation and room for further ridership growth, as well as a new glass train shed.

Union Pearson Express

The Union Pearson Express will provide a high-quality, express rail service connecting Union Station in downtown Toronto with Terminal 1 at Toronto Pearson International Airport.

The Government of Ontario asked Metrolinx to build, own and operate the Union Pearson Express in July 2010, and since then, considerable progress has been made to ensure the project is delivered on time and on budget, while leveraging existing infrastructure improvement initiatives. Infrastructure improvements currently underway along GO Transit’s Kitchener line (formerly the Georgetown line), and upgrades being undertaken at Union and Bloor stations will support both GO Transit and the Union Pearson Express. In the spring of 2012, construction began on a new three-kilometre rail spur which will branch off from the Kitchener corridor near Highway 427 and connect the Union Pearson Express to a new passenger station at Toronto Pearson Terminal 1.

The Union Pearson Express is part of an integrated transit strategy for the Greater Toronto and Hamilton Area that will create jobs, enhance the quality of life by easing traffic congestion and fuel economic prosperity. The Union Pearson Express will address a significant transportation gap in airport-to-downtown travel in Toronto, and is a critical first step in executing other vital projects outlined in The Big Move – Metrolinx’s forward-looking, regional transportation expansion plan. Each year, more than five million cars travel between downtown and the airport and that number is expected to reach nine million by 2020. The Union Pearson Express is expected to remove 1.2 million car trips from the road within the first year of operation.

In May 2010, GO Transit began rolling out the new PRESTO fare card. PRESTO allows commuters to travel between multiple transit systems in the GTHA using a single card eliminating the need for exact change, tickets or transfers to get on a bus, GO Train or subway.

In March 2011, as part of the new Toronto Transit Plan, the City of Toronto and TTC have agreed to work together with Metrolinx on mutually agreeable terms to implement PRESTO across the TTC system as well.

Toronto Light Rail Transit Projects

The Government of Ontario is moving forward on its commitment to deliver the largest rapid transit expansion in the history of Toronto.

Rapid transit – running above and below ground and connecting Toronto with comfortable, convenient, reliable and fast service – will keep our economy strong, ease congestion, as well as provide an easy connection to subways, buses and GO Transit.

The Toronto rapid transit projects are part of The Big Move. The Big Move is a 25-year, $50 billion plan that will transform regional transportation across the Greater Toronto and Hamilton Region.

The Government of Ontario has committed $8.4 billion in support of new transit for Toronto.

  • The Eglinton Crosstown LRT will add 19 kilometres of new transit from Mount Dennis (Weston Road) to Kennedy Station. See the Eglinton Crosstown fact sheet and website.
  • The Sheppard East LRT will add 13 kilometres of new transit along Sheppard Avenue from Don Mills subway station to east of Morningside Avenue. See the Sheppard East LRT fact sheet.
  • The Finch West LRT will add 11 kilometres of new transit along Finch Avenue from the planned Finch West subway station at Keele Street to Humber College. See the Finch West LRT fact sheet and page.
  • A $1.48 billion investment to replace the current Scarborough RT.

Toronto-York Spadina Subway Extension

The six-station underground subway extension from Downsview Station to Vaughan Metropolitan Centre replaces the shuttle bus connection from Downsview Station to York University that carries a daily average of 20,200 riders. It will be the first subway line to cross a municipal boundary in the region and will support significant new development. This project will be in service in late 2016. Learn more at ttc.ca.

York Viva Bus Rapid Transit (BRT)

In partnership with The Regional Municipality of York, Metrolinx is improving rapid transit through the construction of dedicated lanes in the centre of the road – rapidways – that will allow rapid transit buses to move out of congested traffic. The more than 34 kilometres of planned routes will provide more reliable and more frequent service, connections with GO Transit, regional transit and future extensions of the subway system.

In December 2009, construction began with the first segment along Highway 7 from Markham Centre to Richmond Hill Centre. The first BRT station – Warden Station – opened at Warden Avenue and Enterprise Boulevard in Markham in March 2011. Warden Station is the first of 11 new vivastations to be built along Highway 7 in Markham and Richmond Hill in the next phase of Viva service.

Mississauga Transitway

In partnership with the City of Mississauga, GO Transit is building new, exclusive bus lanes on roads in Mississauga along Hwy. 403.

The Transitway project will be a high-efficiency transit corridor running east-west across Mississauga. The Transitway will support all-station stop and extensive express bus service for thousands of riders per day, making it faster and easier for you to travel to, from and through Mississauga and the GTHA.

In August 2010, construction began on the 18-kilometre east-west busway across Mississauga between Winston Churchill Boulevard and Renforth Drive. A total of 12 stations will be built along the route, with one existing station being incorporated into the busway.

Hurontario-Main Light Rail Transit (LRT) 

A signature project under the Moving Ontario Forward Plan, The Hurontario-Main LRT is funded with a $1.6B commitment from the Province of Ontario, announced by the Minister of Transportation on April 21, 2015.

Led by Metrolinx, the Hurontario-Main LRT will bring 23 kilometres of rapid transit to Mississauga and Brampton. The service will move more people, faster through these corridors than the existing bus service.

The line will include 26 stops, and provide a crucial link between many of the region’s existing transit lines, including GO Transit’s Kitchener, Milton and Lakeshore West rail lines, Mississauga MiWay, Brampton Züm, and the Mississauga Transitway BRT.

Hamilton Light Rail Transit (LRT)

Ontario will provide up to $1 billion to build a new light rail transit (LRT) line in Hamilton as part of the largest infrastructure investment in Ontario's history.

New, modern light rail vehicles on tracks separated from regular traffic will offer speedy service from McMaster University through downtown Hamilton to Queenston Circle. The LRT will connect directly to the new West Harbour GO Station, which is now under construction, and protect for a future, high-order pedestrian connection to the Hamilton Centre GO Station. The LRT will ultimately extend to Eastgate Square. Procurement for the LRT will start in 2017, with construction starting in 2019.
