Late nights Monday, September 20 until Thursday, September 23, Line 1 Yonge - University subway trains in both directions operate along the southbound tracks only between Vaughan Metropolitan and Pioneer Village stations, while TTC crews repair a leak on the northbound tracks. Regular service resumes by 6 a.m. each morning.
(Since the single-track operation occurs after midnight each night, technically, the closure is from Tuesday, September 21 until Friday, September 24.)
During single-track operation, both south- and northbound trains alternate along the southbound tracks.
You must board northbound trains on the southbound platforms at Pioneer Village and Highway 407 stations. You may also have to wait for trains longer than usually.
The TTC is closing this section of Line 1 once more in September:
- Monday, September 27 until Thursday, September 30 - Vaughan Metropolitan Centre to Pioneer Village - Single-track operation after midnight.
