St Clair West Station - fire ventilation upgrade project

Early investigation and overnight noise assessment
Effective February 2024

Timeline: as early as Friday, April 26 2024*
*Pending weather and unforeseen events. Content / timeline accurate at time of printing.

What we are doing and why:

The TTC is planning for capacity improvements at some of Line 1’s busiest subway stations. For more information on this program, please visit our website. Fire ventilation systems across the TTC will be improved as part of the program which will allow for increased system capacity.


As part of early investigation of this project, an archaeological assessment is scheduled to take place in Cedarvale Park as early as April 26. Hand equipment will be used to dig test pits in the park. Excavated soil from test pits will be sifted through wire mesh to aid potential artifact recovery. If cultural resources are unearthed, additional test units and pits may be excavated to gather further information. Upon completion, all test pits and units will be backfilled. This work is projected to last approximately one week.
