1991 Addition
The three story addition to the Metallurgy Building cost $9 million dollars. This addition was supported by a gift of $6.2 million dollars from Lucile Pratt on behalf of her late husband David Lawrence (Lorne) Pratt and funding from the Ontario Ministry of Colleges and Universities and the Information Technology Research Centre. It was renamed the D.L. Pratt Building at the official opening on January 21, 1991. [14]
