There will be no subway service between St. Clair West ad King Stations on Saturday.

On Sunday, there will be no subway service between Bloor-Yonge and Osgoode stations.

During the closures, staff will be upgrading the train’s automatic control signal system.

Dupont Station will be closed, but all other stations will remain open for the sale of fares.
