Memorable Manitobans: Leo Arthur Slater (1896-1984)


Born at Napinka on 13 July 1896, son of Annie Barker and postmaster Andrew Slater, he attended Napinka School, Deloraine School, and the Manitoba Law School, obtaining an LLB degree from the latter in 1922. He was called to the Manitoba Bar that year and, in 1923, he established a private law practice at Morris. He was made a King’s Counsel in 1940. He ran for the Provencher constituency in the 1940 and 1945 federal elections and 1941 provincial election but was defeated each time. After practicing for over 50 years, he retired to Burnaby, British Columbia where he died on 13 June 1984.
