The City is continuing to move forward on the implementation of transportation infrastructure enhancements along the boundary of the City of Toronto and York Region to address existing transportation capacity deficiencies and to support economic growth of the area. This includes:

  1. Widening of Steeles Avenue East from Tapscott Road to Ninth Line (Donald Cousens Parkway) – detailed design underway by the City.
  2. Extension of Morningside Avenue from Steeles Avenue East to Passmore Avenue – construction nearing completion by private landowner through the Planning Act.
  3. Extension of Morningside Avenue from Passmore Avenue to McNicoll Avenue South – detailed design underway by the City.

The timing of construction for the widening of Steeles Avenue East from Tapscott Road to Ninth Line, and Morningside Avenue from Passmore Avenue to McNicoll Avenue South, is subject to the completion of additional analysis, detailed design and available funding.

The study area is located along Steeles Avenue East from Tapscott Road to Ninth Line, and along Morningside Avenue from Steeles Avenue to McNicoll Avenue.

In 2013, the Ministry of the Environment, Conservation and Parks approved an amended environmental assessment (EA) study led by the Regional Municipality of York. This EA identified a range of new and modified transportation infrastructure enhancements, including infrastructure within the City of Toronto’s jurisdiction.

The recommended enhancements include:

  • reconstruction of Steeles Avenue East, widening from two to six traffic lanes for 1.5 km
  • new 1.5 km extension of Morningside Avenue
  • new sidewalks and cycling infrastructure
  • new traffic signals
  • modifications to existing traffic signals
  • three new bridges crossing the Morningside Creek, Rouge River and Neilson Tributary
  • one new rail corridor crossing on Morningside Avenue
  • enhancements to storm water drainage

In 2016, the City commenced the detailed design for both Steeles Avenue East and Morningside Avenue. To support the economic development and employment lands intensification in the area, the City has had to revisit the baseline conditions. This approach has resulted in the required redesign of components of the linear infrastructure and additional studies to address emerging challenges.

Public Drop-In Event – 2016

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.

Status: Detailed design underway.

The 1.5 km segment of Steeles Avenue East between Tapscott Road to Ninth Line (Donald Cousens Parkway) will be reconstructed as a six-lane urban street with sidewalks and cycling infrastructure.

This design will include new bridge crossings at the Morningside River and Rouge River to accommodate the widened Steeles Avenue East.

The 1.5 km extension of Morningside Avenue from Steeles Avenue East to McNicoll Avenue will be constructed as a four-lane urban street with sidewalks. A new multi-use trail along the east side of the new street is also planned.

Although Morningside Avenue will ultimately be one continuous urban street, the design and construction of the extension are following two different planning processes described below.

Steeles Avenue East to Passmore Avenue

Status: Partly constructed as a private road.

The northern segment of the Morningside Avenue Extension between Steeles Avenue East and Passmore Avenue has been substantially constructed by private development following the City’s planning approval process. Installation of a new signalized intersection at Steeles Avenue East is anticipated in early 2021. This road segment will ultimately be conveyed and assumed by the City once complete.

Passmore Avenue to McNicoll Avenue

Status: Detailed design underway.

The southern segment of the Morningside Avenue Extension between Passmore Avenue to McNicoll Avenue is being designed by the City.

The extension of Morningside Avenue will include a new bridge crossing of the Neilson Tributary north of McNicoll Avenue and a new rail corridor crossing at the location where Morningside Avenue will intersect with an existing CP rail line. The rail crossing type approved in the 2013 EA is an at-grade crossing. A review is underway to determine the appropriate type of rail crossing (i.e. at-grade or grade separated) at this location.

Due to the uncertainty of the crossing type at this time, a construction schedule for the south segment of the Morningside Avenue Extension has not been identified.
