He is best known internationally for his appearance as Simmons, the man whom Auric Goldfinger beats at cards in the opening scenes of the James Bond film, Goldfinger. Originally he was to have played Felix Leiter but, at the last minute, fellow Canadian Cec Linder switched roles with him.

In Canada, he had a varied film and TV career, ranging from the early science-fiction series Space Command, to hosting Cross-Canada Hit Parade for several years in the 1950s. In the 1970s he found new fans as the host of the humorous game show This Is the Law.
