Frederick Greystock Robertson (7 March 1909 - 17 September 2002) was a Liberal party member of the House of Commons of Canada.
Robertson was born in Belleville, Ontario and became a physician after receiving his MD degree at the University of Toronto. After working as a doctor in Cobourg, Ontario, he left his practice in July 1948 to work in the canning industry, eventually owning and managing the Cobourg-based Robertson Packers.
He was first elected to Parliament at the Northumberland riding in the 1949 general election and was re-elected for a second term in 1953. Robertson was defeated by Ben Thompson of the Progressive Conservative party in the 1957 election.
Robertson's father, William George Robertson, was a Liberal member of the Ontario Legislature between 1926 and 1929.[2]
