Angus MacIsaac's father, Alexander MacIsaac, was MLA of Guysborough prior to October 1968. Upon Alexander MacIsaac's death, a by-election was called. Angus MacIsaac, then 25 years old, ran, and was first elected to the Nova Scotia House of Assembly on February 11, 1969. MacIsaac ran as a Progressive Conservative and obtained a 371 vote margin of victory.
In 1972, MacIsaac resigned his seat to run federally for the Progressive Conservatives in Cape Breton Highlands—Canso. He made two unsuccessful attempts to win the seat in the 1972 and 1974 federal elections.
MacIsaac made a successful return to political office in the 1999 provincial election, running in the electoral district of Antigonish. He won the seat with just 12 votes more than the Liberal incumbent.
During his career in provincial politics, MacIsaac served as Minister of Health, Minister of Education, and Minister of Housing under John Hamm, and during his tenure in Rodney MacDonald's government, served as Deputy Premier, Minister of Transportation and Public Works, Minister of Economic Development, and was the Minister of the then newly formed Department of Gaelic Affairs.
When not holding political office, MacIsaac taught at Junior High School and Senior High School levels in Calgary, Canso, Antigonish, and Guysborough.
MacIsaac is married to Mary Ann (née Milner). They have two children.
