Prior to entering Canadian federal politics, Roderick Blaker, commonly known as Rod Blaker, was a lawyer and broadcast editorialist. He was first elected at the Lachine electoral district in the 1972 federal election and was re-elected in 1974, 1979 and 1980. He served consecutive terms in the 29th to 32nd Canadian Parliaments then left federal politics in 1984 without campaigning in that year's federal election.
During his time in Parliament, Blaker had several roles as a Parliamentary Secretary to the Minister of Supply and Services (1976-1977), the Solicitor General of Canada (1977-1978) and the Minister for International Trade (1984).
