Due to signal upgrades and testing, Line 1 of the TTC subway system will be closed this weekend from Downsview to St. George station.
Shuttle buses will be available for commuters along the route.
Due to on-street construction, shuttle service will operate between Downsview and Lawrence West stations throughout the duration of the closure.
The TTC is also reminding those customers traveling on Line 2 who wish to go northbound, should transfer at Yonge-Bloor station as there will be no shuttle service at St. George station.
Alternative routes for surface vehicles will be available.
