Ontario Line Community Notice: Queen-Spadina south site construction update
- Expected duration: The current excavation cycle, which includes rock breaking and structural work, is expected to continue through early 2026.
- Hours of Work: As early as November 19, 2025, the hours of work at the south site will be adjusted to reflect the current stage of work and efficiently complete the required excavation activities.
- Work is expected to start at 7 a.m. and continue up to 2 a.m., Monday through Friday.
- Crews may also work on Saturday and Sundays from 7 a.m. to 5 p.m. • All work schedules are subject to change, and weather permitting.
Excavation at the Queen-Spadina south site has entered its final stage, with rock breaking and structural work continuing through early 2026. Beginning November 19, 2025, work hours will extend from 7 a.m. to 2 a.m. on weekdays, with weekend shifts as needed, subject to weather and schedule changes.
The reason for the extension is to complete this work as quickly as possible and move into the less intrusive phases of construction. Crews will be using a specialized roadheader that is expected to be quieter than the previous roadheader used, with proven success at other sites. To minimize disruption during extended work hours, crews will primarily rely on this equipment instead of traditional hammer-style excavators, materials will be removed via the Queen-Spadina north site to reduce crane and machinery activity at the south site, and continuous noise and vibration monitoring will remain in place to track impacts. Please see attached notice for more details.
