Lawyer, MLA (1927-1932), MLA (1933-1936), MLA (1937-1940), MLA (1941-1945), MLA (1946-1949), MLA (1950-1953).

Born at Balderson, Ontario on 4 September 1891, son of John McLenaghen and Elisabeth McIlquhan, he was educated at Balderson before the family settled at Portage la Prairie. He attended the Portage Collegiate Institute and the University of Manitoba (BA). He was articled in law to Arthur Meighen and was called to the Bar in 1918. He practised with W. R. Sexsmith at Portage la Prairie for a year, then went to Selkirk where he continued his legal career, and was made a King’s Counsel in 1937.

On 29 March 1919, he married Catherine Maria Newman of Portage la Prairie, with whom he had a son and a daughter. He was first elected Conservative MLA for Kildonan in 1927, and was re-elected in 1932, 1936, 1941, 1945, and for the new St. Andrews riding in 1949. He held the portfolios of Health (1940-1944), Attorney General (1941-1950), and Labour (1944-1946). In August 1931, McLenaghen joined Selkirk Mayor J. J. Bell to lobby Public Works Minister W. R. Clubb to develop a bridge across the Red River at Selkirk as a relief project. The bridge was completed in 1937. In 1932, he was elected to the Selkirk School Board and served as its Chair as of 1934.

He died at his home in Little Britain on 23 June 1950 and was buried in Little Britain Cemetery. There are some papers at the Archives of Manitoba.
