In 1924 he gained an appointment as assistant professor at McGill University in Montreal, where he taught physics. He became associate professor in 1930.

During World War II he served as a liaison officer for the National Research Council, working at the MIT-run Radiation Laboratory on radar research and development. He developed a fast-scan radar antenna that became known as the "Foster scanner".
