Over the years, complex reactions between chemical treatments, building envelope and structure, had caused deterioration of all building elements. These reactions, in combination the site’s extreme exposure to Lake Ontario, forced the City into a very major program of repair and reconstruction to the operating facility.

THA conserved material and assembly aspects of limestone, expansive copper roofs, skylights, metal-work and, in the course of the work, developed a new clay brick to replicate the building’s signature material. THA also developed a glazing system that was impact resistant, double-glazed, and controlled ultraviolet light for selective replacement of existing windows.
