In 1893 he emigrated to Canada and found employment at the firm of Edward Maxwell (1867-1923) in Montreal, working as a draughtsman and assistant to Maxwell. Archibald stayed at the firm until 1897 when he formed a partnership with another former Maxwell draughtsman, Charles Jewett Saxe (1870-1943). This partnership continued until 1915 at which time Archibald began to practise alone. He designed a variety of structures including a number of stations and hotels for the Canadian National Railway; he designed several sports buildings including the Montreal Forum, a number of schools, churches, commercial buildings, and hospitals, as well as residential buildings in Montreal and Kingston. Noteworthy among his many projects is the Masonic Memorial Temple in Montreal (1928). Upon his death in 1934, Archibald's practice was continued by his son Ian T.

John Smith Archibald (1872-1934) reçut ses premiers rudiments de formation en architecture au cabinet de William MacIntosh, dans sa ville natale d'Inverness (Ecosse).
