Ontario Begins Groundwork for Hazel McCallion Line Extension into Downtown Brampton

BRAMPTON, Ontario — The Ontario government has launched preliminary ground investigations for a planned extension of the Hazel McCallion light rail transit (LRT) line into downtown Brampton, marking a new phase in efforts to improve regional transportation, reduce traffic congestion and support economic development across Peel Region.

The province announced on November 9, 2026, that crews have begun drilling boreholes along Main Street and nearby roads to assess underground conditions for the proposed extension, which will span more than three kilometres.

The project is intended to bring rapid transit closer to residential neighbourhoods, employment centres and commercial districts in one of the Greater Toronto Area’s growing municipalities.

Ontario Advances Downtown Brampton Rapid Transit Expansion

The preliminary drilling program will provide engineers and project planners with information about soil composition and subsurface conditions. These findings will help determine appropriate construction methods and equipment requirements as the extension moves through its planning and design stages.

The proposed route will connect the Brampton Gateway Terminal at Steeles Avenue East with the Brampton Innovation District GO Station in the downtown core.

Once completed, the extension is expected to improve connections with Brampton Transit and Züm services, giving commuters additional options for travelling within Brampton and throughout the Greater Toronto Area.

“People in Brampton deserve a transit system that keeps pace with their growing city, and we’re taking the next step to make that happen,” said Prabmeet Sarkaria, Minister of Transportation. “By extending the Hazel McCallion Line into the heart of downtown Brampton, we’re connecting more people to jobs, businesses and opportunities while taking more cars off the road. We’re making investments to build a faster, better-connected transportation network that will serve Brampton families for generations to come.”

Extension Expected to Support Businesses and Regional Connectivity

Improved public transportation access could benefit downtown Brampton businesses by expanding connections between commercial areas, residential communities and employment destinations.

The extension will build on the existing 18-kilometre Hazel McCallion Line corridor, designed to connect Brampton and Mississauga through 19 stops.

Light rail vehicles are currently undergoing testing along the main corridor. The downtown Brampton and downtown Mississauga extensions are being advanced as separate projects.

“Expanding the Hazel McCallion Line into downtown Brampton is an important step toward building a stronger, more connected Peel Region. By improving access to reliable public transit, we’re making it easier for residents to get to work, supporting local businesses and creating more opportunities for families across Mississauga and Brampton.”

Local Officials Emphasize Economic Benefits

Brampton Mayor Patrick Brown welcomed the start of preliminary investigations while calling for the project to advance quickly toward construction.

“Extending the Hazel McCallion Line into downtown Brampton will give residents a direct connection to Brampton GO and make it easier to get to work and visit local businesses. It’s a connection our growing city needs. We thank the Ontario government for getting this work underway and urge them to move quickly from design to construction and get the extension into service as soon as possible.”

— Patrick Brown, Mayor of Brampton

Hardeep Grewal, MPP for Brampton East, also highlighted the potential benefits for residents and businesses.

“Bringing rapid transit into downtown Brampton means better connections to jobs, more customers for local businesses and more ways for families to get around. This early work is an important step toward building the transit network our growing city needs.”

Geotechnical Investigations Will Guide Construction Planning

Metrolinx, the provincial transit agency responsible for major regional transportation projects, said underground investigations are essential for determining construction requirements.

“Few places in the world are doing more tunneling for transit projects than Ontario. The start of geotechnical investigations represents a critical step in any such project. This work will give us a better understanding of soil conditions in a way that directly influences the equipment we will use to get the job done. We know that this work can be disruptive to local businesses and communities and we will continue to work diligently to keep people informed, safe, and moving.”

Part of Ontario’s Nearly $70 Billion Transit Investment

The Brampton extension forms part of Ontario’s broader transportation expansion program, which includes nearly $70 billion in transit investments and what the province describes as North America’s largest transit expansion.

Although the government has not provided a construction completion date or specific project budget for the downtown Brampton extension, the commencement of geotechnical work represents an important preparatory milestone.

The project’s longer-term economic impact will depend on construction timelines, integration with existing transportation services and its ability to improve commuter access.

For Brampton residents and businesses, the proposed extension represents another step toward a more connected regional transit network designed to accommodate population growth and future economic activity.
