The jarring sounds of rock breaking will fill the air at a key Toronto intersection as part of a long-term transit project — and the noise is expected to continue 24 hours a day until next summer. Ontario Line construction is one of the handful of provincial infrastructure projects using shifts of crews working 24-hour construction, greatly improving build times but coming with some caveats for local businesses in the interim. Metrolinx has announced that it will begin the second phase of excavation for Queen Station in November, which will involve the excavation of bedrock from the station site. Though the work planned is inherently loud, Metrolinx states that "Crews will take measures to minimize noise impacts wherever possible, [along with] air quality, noise, and vibration monitoring, as well as plywood hoarding and mud mats for dust suppression." Among the measures being taken, Queen Station is one of the handful of locations where Metrolinx is employing massive acoustic shelters to create a noise buffer between the construction work within and the surrounding city.
