Transportation - Yonge North Subway Extension

← Return to Environmental Project Report Overview

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 (currently limited to southernmost portion), and bus options, including the TTC, GO Transit and VIVA commuter lines. Freight trains operated by Canadian National Railway and Canadian Pacific Railway are also present.
  • Existing means of transportation/transportation networks (including personal vehicles, transit, walking, cycling and rail) have the potential to be temporarily impacted during construction activities. Appropriate mitigation measures (see Potential Effects & Mitigation Measures on next slides) to be implemented during construction are anticipated to reduce or eliminate the potential impacts to the transportation network users.
  • During project operations, minimal short-term impacts associated with maintenance activities (e.g., temporary lane/sidewalk closures) may occur. Consultation with local transportation agencies will occur should any potential modifications to the local transportation network, such as adjustments to transit service schedules, be required.

Potential Effects & Mitigation Measures

Potential Effects:

Construction Phase

  • Potential for temporary road lane, sidewalk, or bike lane closures.
  • Potential re-alignment of road, sidewalk, or bike lanes in the area.
  • Potential for access restrictions to local bus routes.
  • Potential disruptions to rail services (e.g., CN Freight services) in the impacted area.
  • Potential changes to special traffic lanes (e.g., removal of HOV lanes).
  • Potential implementation of turn prohibitions at intersections.
  • Potential changes to on-street parking regulations in the area.
  • Potential changes to transit services schedules and routes.

Operational Phase

  • Minimal short-term impacts associated with maintenance activities (e.g., temporary lane/sidewalk closures) may occur.
  • Potential for modifications to the local transportation network, such as adjustments to transit service schedules.

Mitigation Measures:

Construction Phase

  • Traffic Control and Management Plan(s) will be developed prior to construction.
  • Access to nearby land uses will be maintained to the extent possible. Potentially affected residents, tenants and business owners will be notified of upcoming construction work and potential traffic impacts.
  • In the event closures of sidewalks or bike lanes are necessary, safe alternative paths will be provided.
  • Consult with rail operators with current service along the rail corridor (i.e., Canadian National Railway) to assess how track closures, if necessary, would impact their service and co-ordinate temporary schedules to accommodate all rail services on the open tracks.
  • Ensure public is notified of the changes to turn prohibitions at intersections via additional signage.
  • Ensure public is notified of changes to curbside lane regulations (e.g., parking, HOV lanes) via additional signage.
  • Ensure that the public is notified in advance of any potential public transit service disruptions.

Operational Phase

  • Provide signage and detours in advance of temporary lane/sidewalk closures during maintenance activities, as required.
  • Consult with local transit agencies regarding the potential changes to the local transportation network.
