Toronto Transit Commision (TTC) Union Station

The redesign of the Toronto Transit Commission’s primary station involved the renovation of the existing concourse level at Union Station, modification of the existing Union Station platform to serve the University Line and the construction of a new platform to better serve the Yonge Line. The project is one of Waterfront Toronto’s and the TTC’s priority projects. For this multi-faceted, composite project, LRI prepared an approach to station emergency ventilation to improve the existing performance level of Union Station. We collaborated with the City of Toronto to discuss this approach and the degree of compliance with the Building Code, which was ultimately deemed satisfactory by the City.

Union Station remained open throughout the transformation, which posed a challenge in terms of coordinating with GO Transit and local businesses while maintaining a customer-centric approach.

LRI provided building code review services to the design team so that the improvement plans addressed the Life Safety needs of passengers and pedestrians. The team provided an extensive suite of services, including the review of drawings, preparation of Building Code approaches and reports, performance-level evaluations, development of interpretations to address unique design challenges and negotiations with the Authority Having Jurisdiction (AHJ).
