Traffic & Transportation - Environmental Impact Assessment Report

← Return to Draft Environmental Impact Assessment Report

Key Findings

  • The Study Area includes a substantial road network and is served by both local and regional transit networks through a range of train, subway, streetcar and bus options, including the TTC, GO Transit and VIA Rail commuter lines. Freight trains operated by Canadian National Railway and Canadian Pacific Railway are also present.
  • An active transportation network is present across the Study Area including major multi-use pathways, minor multi-use pathway connecting trails, sidewalks, and on-street bike lanes.
  • A new multi-use trail will be constructed as a result of the Ontario Line.
  • Planned mitigation measures will permanently enhance the downtown streetcar network.
  • During construction, lane restrictions/closures, travel time delays, realignment of sidewalks and bike lanes, and rail service restrictions will be temporary and reduced with appropriate mitigation measures (See Potential Effects & Mitigation Measures).

Potential Effects & Mitigation Measures

Potential Effects

Construction

  • Construction will result in the need for temporary, partial, and full lane, street, sidewalk and trail closures.
  • Queen Street between Yonge Street and Victoria Street will be closed for approximately 6 months. Queen Street west of Victoria Street will be closed for the duration of the Queen Station construction.
  • Increase in construction vehicle traffic may cause impacts to traffic flow on the local road network.
  • Temporary, partial, or full closures of sidewalks, trails, pedestrian and cyclist pathways.
  • Construction may result in access restrictions to local bus routes, temporary changes in bus stop shelters/locations, and temporary disruptions to the existing rail corridor.

Operation

  • Traffic improvements are anticipated as a result of operations.
  • The connection between Banigan Drive and Thorncliffe Park Drive will be permanently closed.
  • The increased pedestrian demands generated in the vicinity of Ontario Line stations may coincide with increased delays and worsened pedestrian levels of service for existing pedestrian trips that are not taking the Ontario Line.

Mitigation Measures

Construction

  • Develop and implement a Transit and Traffic Management Plan prior to construction in consultation with local transportation and transit authorities.
  • Issue notifications and advisory signage to alert traffic and transit users of any upcoming road closures and disruptions as required.
  • Ensure the appropriate signage and notifications are provided to safely direct pedestrians and cyclists around closed active and transit network sections.
  • Access to nearby lands and businesses will be maintained to the extent possible.

Operation

  • Signage and advance notification are recommended to notify station users of any detours.
  • Increase the surface transit stop area through either the removal or relocation of sidewalk furniture and increasing surface transit frequency/capacity should be considered, where feasible.
