Ralph FergusonPC (September 13, 1929 – August 30, 2020) was a Canadian farmer and politician.
Ferguson was a farmer in south-western Ontario and co-founder of the Lambton Pork Producers Association. In the late 1950s, he was chairman of the Lambton County Egg Producers.
Ferguson's cabinet career was short-lived, however, as both he and the Turner government were defeated in the September 1984 federal election.
As a backbench MP, Ferguson participated in several trade missions as an advocate of export market expansion. He also played a role in the creation of the Canadian Agricultural Export Corporation or CANAGREX, a crown corporation formed in 1983 and disbanded by the Mulroney government in 1987. As minister, he established the first controlled environment seed bank in an effort to protect parent seed stocks.
