In the 1945 and 1948 Ontario elections he ran as a Liberal-Labour candidate but lost on both attempts until his election to the Ontario legislature as a Liberal MPP in 1951. He remained in office until the 1967 Ontario election.

A pro-labour politician, he ran for the Ontario Liberal leadership in 1958 but won only 32 votes and was eliminated on the first ballot along with Liberal-Labour MPP Albert Wren .
