Ontario Expanding GO Transit Rail on the Stouffville Corridor

Providing More GO Transit Service for Commuters

Ministry of Transportation

Today, through funding made available under the Moving Ontario Forward plan, Ontario announced another milestone to expand GO Transit rail service on the Stouffville corridor as part of GO Regional Express Rail (RER).

Metrolinx and Infrastructure Ontario issued a request for qualifications (RFQ) for interested parties to design and build the infrastructure that is needed to support expanded GO rail service on the Stouffville Corridor that includes infrastructure upgrades at three GO Stations:

  • Milliken Station: new and relocated platforms with canopy enclosure, tunnels, elevators, Steeles Avenue pedestrian connection, Steeles Avenue crossing improvements, and customer amenities
  • Agincourt Station: new second track, new and relocated platforms with canopy enclosure, tunnels, elevators, customer waiting areas, building relocation, and  customer amenities
  • Unionville Station: new second track and turning track, new and relocated platforms with canopy enclosure, tunnels, elevators, parking expansion, and customer amenities

GO RER is one way Ontario is providing faster, more frequent and more convenient transit service across the Greater Toronto and Hamilton Area. GO RER also involves the introduction of electrification of core segments of the GO Transit network (including the Stouffville Corridor) by 2024. The program will also help manage congestion, connect people to jobs, and minimize greenhouse gas pollution by reducing car trips and improve travel times.

Ontario is making the largest investment in public infrastructure in the province's history -- about $160 billion over 12 years starting in 2014-15.  Planned investments would support over 110,000 jobs, on average, every year across the province, with projects such as roads, bridges, transit systems, schools and hospitals. In 2015, the province announced support for more than 325 projects that will keep people and goods moving, connect communities and improve quality of life. 

Investing in GO Transit rail expansion is part of the government's economic plan to build Ontario up and deliver on its number-one priority to grow the economy and create jobs. The four-part plan includes helping more people get and create the jobs of the future by expanding access to high-quality college and university education. The plan is making the largest infrastructure investment in hospitals, schools, roads, bridges and transit in Ontario's history and is investing in a low-carbon economy driven by innovative, high-growth, export-oriented businesses. The plan is also helping working Ontarians achieve a more secure retirement.

Quick Facts

  • The RFQ is the first step in the procurement process to select a team to deliver the project. Teams who qualify will be invited to respond to a request for proposals later this summer.
  • Through the Moving Ontario Forward plan, $31.5 billion in dedicated funds is being made available over 10 years for transit, transportation and other priority infrastructure projects across the province.
  • GO RER will provide faster and more frequent GO rail service across the region, with electrification of core segments of the network. Weekly trips across the entire GO rail network are expected to grow from about 1,500 to nearly 6,000 over 10 years.
  • The investments in station upgrades and grade separation will support future electrification of the Stouffville GO corridor from Union Station to Lincolnville.
  • Since 2003, Ontario has extended GO’s rail network by nearly 90 kilometres, opened 14 new GO stations, rebuilt four existing stations, and added more than 31,000 new parking spots across the system.
  • Research shows that investing a dollar in public infrastructure in Canada raises GDP by $1.43 in the short term and up to $3.83 in the long term.

“This procurement shows our commitment to implement much needed rapid transit infrastructure in the GTHA. Rapid transit expansion is all about giving people more transit options and making it as easy as possible for people to choose transit first. This is proof of our government’s plan in action. We are committed to providing accessible, modern transit infrastructure that will manage congestion, reduce commute times, create jobs and improve the quality of life for Ontarians.”

Steven Del Duca

Minister of Transportation

“Making improvement to existing stations along the Stouffville GO line is the next step in our plan to improve transit for residents in the GTHA. These station improvements will enable us to provide two-way, all-day service to residents living in Scarborough and Markham and builds on the recent approval received to add new GO stations to our existing network.”
