Career
He played baseball as a catcher with the Vita Cubs, Tolstoi Jets, Winkler Royals and Rossburn. Derewianchuk was named to the Manitoba Baseball Hall of Fame in 2007. In the provincial election of 1973, he defeated Progressive Conservative candidate Garnet Kyle by 437 votes.
A strong showing by Liberal Mark Smerchanski may have split the centre-right vote, and contributed to Derewianchuk"s victory.
Derewianchuk was the first, and to date the only, candidate of the NDP to be elected in the rural, southeastern riding of Emerson. He does not appear to have played a major role in the legislature.
His time in office was short-lived, as he was defeated by Tory candidate Albert Driedger in the 1977 election. He has not sought a return to provincial politics since this time.
