He returned to work for the NRC in 1955 as a research officer, followed by a promotion to head of the Free Radical Chemistry Section. He was awarded the 1968 Petroleum Chemistry Award, the 1988 Linus Pauling Award, and both the Davy Medal and Royal Medal of the Royal Society, the latter for "elucidating the mechanism of reactions involving free radicals". In 1995 he was made an officer of the Order of Canada. He has received honorary degrees from the universities of Guelph, Mount Allison, St Andrews, Carleton, McMaster and Dalhousie.
