In order to accommodate the construction of the Metrolinx Ontario Line Subway Project while maintaining existing service to Enbridge Gas customers, Enbridge Gas has proposed a new project in the City of Toronto.

The proposed Overlea Station Relocation Project will include the decommissioning and construction of various natural gas stations and pipelines in the area of Thorncliffe Park.

Enbridge Gas has identified one preliminary preferred route, due to urban constraints limiting routing options. The preliminary preferred route includes the following construction:

  • 1100 m of 8-inch natural gas pipeline, along Overlea Boulevard, from Millwood Road to Thorncliffe Park Drive.
  • 340 m of 4-inch pipeline, on Metrolinx-owned private property in the area.
  • 100 m of 4-inch pipeline along Leaside Park Drive.
  • 50 m of 6-inch pipeline along Thorncliffe Park Drive.

The proposed station construction includes:

  • A new natural gas regulating station on Leaside Park Drive.
  • A new natural gas regulating station on Thorncliffe Park Drive.

The proposed decommissioning of previous assets includes:

  • 1000 m of 12-inch natural gas pipeline along Overlea Boulevard.
  • 360 m of 4-inch pipeline, between Overlea Boulevard and Banigan Drive.
  • 115 m of 4-inch natural gas pipeline, along Leaside Park Drive and Thorncliffe Park Drive.
  • 50 metres of 6-inch natural gas pipeline along Thorncliffe Park Drive.
  • A natural gas station located at the intersection of Millwood Drive and Overlea Boulevard.
