Anticipated Impacts

Motorists traveling northbound on Richardson Avenue will have to turn right onto Byron Avenue. There will be no access to Richardson Avenue southbound from Richmond Road. 

Motorists should adhere to detours, traffic control signage, posted speed limits, allow for added travel time and use extra caution when moving through active construction corridors as traffic patterns change.

Pedestrians and cyclists should use extra caution and adhere to posted signage when localized detours are in-place, to ensure safety.

The construction work outlined in this notice is subject to change. Work may be delayed or extended due to weather or other unforeseen circumstances.


Accessibility is an important consideration for the O-Train Extension project. The O-Train Extension team makes every effort to provide access through and around construction sites. If you require special accommodation, please contact

The safety of the public and workers is paramount, and we thank you for your patience during construction.
