Malcolm A. MacKay (January 29, 1944 – January 25, 2025) was a Canadian politician. He represented the electoral district of Sackville in the Nova Scotia House of Assembly from 1978 to 1984. He was a member of the Nova Scotia Progressive Conservative Party.^[1]

MacKay was born in Dartmouth, Nova Scotia on January 29, 1944. Educated in Montreal at Sir George Williams University and Collège Sainte-Marie de Montréal, he was a telephone technician. In 1962, he married Claudia June Burns.^[2]

After serving two years on Halifax County Council,^[2] MacKay entered provincial politics in the 1978 election, defeating Liberal incumbent George Doucet in the new Sackville riding.^[3] He was re-elected in the 1981 election.^[4] In the 1984 election, MacKay was defeated by New Democrat John Holm, finishing third behind Liberal Bill MacDonald.^[5] Controversy arose during the campaign, when MacKay admitted he used a false address to claim expenses as a member living away from the capital.^[6][7] In April 1985, an Auditor General's report asked MacKay to repay over $7,000 in extra expenses.^[8] The money was paid back and MacKay was not charged criminally.^[9]

In February 2004, a political comeback bid ended when MacKay's candidacy for the Conservative nomination in Halifax West for the 2004 federal election was rejected by the party.^[9][10] MacKay attempted to return to provincial politics in the 2006 election, running for the Nova Scotia Liberal Party in Hants East,^[11] but finished third.^[12]
