John B. Parkin Associates was a Canadian architectural firm based in Toronto that operated from 1947 to 1969. During its life, it was the largest architectural practice in Canada and today is recognised as the country's leading proponent of modern architecture in the post-war era. The partnership was formed between John Burnett Parkin, his brother Edmund T. Parkin, and the younger, unrelated John Cresswell Parkin. John Burnett served as the firm's principal, while John Cresswell served as partner-in-charge of design.
