“Our client performs as a General Contractor and they are demolishing some structures and buildings in downtown Toronto. The Consultant requires 24/7 real time noise monitoring at the worst case noise impact locations close to high rise residential buildings in order to protect the public interest while the site activities are ongoing. We have been using EM2030 for a couple weeks and we love its stability and function on the cloud.”

Situated at the pivotal intersection of Yonge and Bloor streets, Bloor-Yonge Station stands as the TTC’s busiest station. Having opened its doors in 1954, it serves as a major interchange between Line 1 and Line 2. Notably, by 2019, the daily average weekday ridership on Line 1 alone surpassed 825,000, earning it a rank among North America’s most frequented transit lines. With the population of the GTA on the rise and several transit expansions on the horizon, it became evident that the station necessitated both expansion and modernization to cater to the evolving needs.
The comprehensive retrofit and expansion project for the station has been designed to meet both current and future ridership demands. Key elements of this project include the expansion of both Line 1 northbound and southbound platforms, the introduction of a new platform to cater to eastbound passengers on Line 2, and the reconfiguration of the existing Line 2 platform to serve westbound passengers. In addition, infrastructural enhancements are on the cards, with plans for a new barrier-free entrance, an additional exit leading to Bloor Street, and other amenities such as new escalators, elevators, and station finishes. Further augmenting the station’s facilities will be a new electrical substation, fan plants for improved ventilation, and essential utility upgrades. An exciting phase post-completion will see the activation of platform edge doors on Line 1, thanks to the pre-existing ATC signal system. Simultaneously, groundwork for future platform edge doors on Line 2 will be laid, contingent upon the installation of the full ATC signal system.
Safety and accessibility are at the heart of this project. Every design nuance has been tailored to adhere to the standards set by the Accessibility for Ontarians with Disabilities Act, 2005 (AODA) and the Ontario Building Code. By integrating features like barrier-free entrances and additional elevators, the project aims to foster an inclusive transit experience for all.
As for the construction timeline, advanced construction activities began in May 2023. This phase entailed the removal of specific buildings, paving the way for a new and accessible subway entrance. Alongside, the former carwash at 830 Church Street was taken down to establish a new fan building, essential for enhanced air circulation within the station. Advanced utility relocation activities on Bloor Street East have been marked for Q3 2023, leading up to the commencement of major construction activities in 2024.
The Bloor-Yonge Station Capacity Improvements project symbolizes TTC’s unwavering dedication to delivering a seamless, safe, and accessible transit experience in the face of growing ridership challenges.
THE PROBLEM
The project is centrally located in a high- traffic area. The project team identified a need for 24/7, real-time noise monitoring at the worst case noise impact locations close to high rise residential buildings, inorder to protect the public interest while demolition and construction activities are ongoing on site.
