Infrastructure Ontario/Metrolinx

This project was, at the time, the largest transit expansion in Toronto’s history, and one of the largest P3 projects in North America. It is estimated to move people 60% faster than existing bus service and accommodates ten times as many passengers.

The new light rail transit line runs along Eglinton Avenue between Mount Dennis Station (Weston Road) in the west and Kennedy Station in the east. The 19-kilometre corridor includes a 10-kilometre underground portion between Keele Street and Laird Drive. The line features 25 stations and stops, with links to bus routes, 3 subway stations and various GO Transit lines. HH Angus provided mechanical and electrical consulting engineering for three stations – Mt. Pleasant, Leaside (Bayview) and Laird.

HH Angus’ mechanical scope included ventilation and air conditioning of services spaces, sanitary and storm drainage throughout the station, track level and specialty trackwork drainage, fire protection systems for retail and service areas, water efficient plumbing fixtures and energy efficient HVAC systems.

The electrical scope covered power distribution, lighting and communications systems. Design layouts were provided for power distribution of the subway station, as well as traction power for the trains.

The lighting design featured reduced power consumption. Exterior public areas lighting designs incorporated increased daylight levels, LED lighting in pylon signs, and energy efficient lighting in illuminated wayfinding signage to minimize power consumption.

Communications systems design included fire alarm protection, public address speakers, passenger intercom, TTC pax telephones, public telephones and security systems including closed circuit television.
