John Hnatyshyn (; Ukrainian: Іва́н Миха́йлович Гнати́шин|Iván Mykháylovych Hnatýshyn, in Ukrainian pronounced as /iˈwɑn mɪˈxɑjlowɪdʒ ɦnɐˈtɪʃɪn/; January 20, 1907 – May 2, 1967) was a Ukrainian Canadian lawyer, Senator and father of Ray Hnatyshyn, the twenty-fourth governor general of Canada.
Born in the mostly Ukrainian northern part of the Austro-Hungarian Duchy of Bukovina,[1] the son of Michael and Anna, Hnatyshyn came to Canada when he was two months old.[2] Raised on a farm near Canora, Saskatchewan, he received a Bachelor of Arts degree in 1930 and a Bachelor of Law degree in 1932 from the University of Saskatchewan.[2] He was called to the Saskatchewan bar in 1933 and practised law in Saskatoon, co-founding the firm of Kyle, Ferguson and Hnatyshyn in 1942 and becoming Queen's Counsel in 1957.[2]
While attending university in Saskatoon, he resided at the Petro Mohyla Ukrainian Institute, where he met Helen Pitts.[3] They married in 1931 and had four children: Ramon, Victor, David and Elizabeth.[2] [3]
In the 1935, 1940 and 1945 federal elections, he tried unsuccessfully to get elected to the House of Commons of Canada as a Conservative candidate for the riding of Yorkton.[2] He also ran unsuccessfully for the provincial legislature as a Progressive Conservative candidate for Saskatoon City in 1952.[2]
In 1959, he was appointed by John Diefenbaker to the Senate representing the senatorial division of Saskatoon, Saskatchewan, becoming Canada's first Ukrainian-born senator.[4] [5] He died in office in 1967.[6]
