In 1964, Terminal One at the Lester B. Pearson International Airport in Toronto opened for service. When constructed it was considered an architectural masterpiece and lauded as a state-of-the art aircraft/passenger processing facility. However, with the progressive development of a brand new, much larger terminal facility, the old Terminal One days were numbered. On November 3, 2004, the last piece of the structure was demolished. The purpose of this technical paper is to outline the design process implemented in the Decommissioning and Demolition of the old Terminal One. Environmental sustainability, a multi-faceted key approach for this immense and rare undertaking, addressed hazardous material decommissioning, demolition methodology, material salvage, recycling and processing. The decommissioning of hazardous substances was an integral activity and a prerequisite to the ensuing stage of demolition in which the process of salvaging and recycling of the demolition materials structural demolition was of prime importance to the stakeholders.
