The City of Toronto is beginning to develop detailed engineering designs for a 1.5 km widening of Steeles Avenue East from Tapscott Road easterly to Ninth Line and the extension of Morningside Avenue to Steeles Avenue. Approval was received in 2013 from the Province of Ontario to move ahead with the project. The engineering design work will require detailed investigations of below surface conditions, coordination with utility companies, permits from approval agencies and property acquisition. The project includes the following improvements:

  • Widening Steeles Avenue: 3 lanes in each direction, sidewalk on both sides, cycle tracks on both sides
  • Extending Morningside Avenue: 2 lanes in each direction, sidewalk on both side,  multi-use trail on east side
  • Construction of 3 new bridges over the Neilson tributary, Morningside Creek and Rouge River

Detailed design and refinements for Morningside Avenue remain ongoing, and works will be completed in two segments.

In 2011, York Region completed an Environmental Assessment Study for Transportation Improvements  from Donald Cousens Parkway to Morningside Avenue. Following completion of the Study, the City of Toronto began a detailed design process for construction of the recommended road network, bridge structures, electrical and utility upgrades.

A public open house was held on July 19, 2016 to share information about the work plan, and meet with City staff and local Councillor Raymond Cho. View the meeting notice and presentation panels below.
