Donald Morris McGregor (April 25, 1923[1][2] – July 25, 2003) was a politician in Manitoba, Canada.
The son of Dan McGregor, he was educated in Lenore schools, and served in the Royal Canadian Navy.
He was re-elected with a comfortable majority in the provincial election of 1966,[1] and supported the governments of Dufferin Roblin and Walter Weir as a backbench MLA.
In the provincial election of 1969, he defeated incumbent Liberal MLA Earl Dawson[1] by 590 votes after redistribution forced them to compete against one another.
McGregor was known as an aggressive defender of his constituents' interests throughout his time in office, and was often regarded as a political maverick.
