William Morrison,, (April 20, 1878 - March 16, 1947) was Mayor of Hamilton, Ontario, Canada, from 1935 to 1943.
First serving as a lawyer and, later, a Crown Prosecutor, Morrison was first elected as an alderman for Ward 2 in 1921. He was re-elected in 1922. Two years later, he secured a seat on the Board of Control. He was elected in a by-election in 1928 as the Conservative Party Member of Provincial Parliament for Hamilton East. He was re-elected in 1929, and served until he was defeated in 1934. During his time with the Conservatives he nominated Colonel George Drew as leader of the party.[1]
He returned to Hamilton and was elected mayor in 1935, a position in which he served until 1943. He was elected (annually) eight times, a record to that date. He served as President of the Ontario Mayors' Association and was a member of the Dominion Mayors' Association.[2] He married Lucy Musson Weir, and had one son, William Robert Morrison, (1912–1983), who became a provincial court judge in Hamilton. His grandson, William R. Morrison, is a Canadian historian.
