Donnie MacIsaac was involved with sports for 45 years: 30 of those in broadcasting with CJFX radio in Antigonish, and CJCB radio and television in Sydney. He began as a sport reporter and hockey play-by-play man with CJFX while he was a student at St. Francis Xavier University in 1948. In 1950, he became sports and news director at CJCB radio. He held both of those positions, while also being the sports director for CJCB television, until 1977, when he switched gears to be communications officer with DEVCO.

He did, however, remain involved with sport through a multitude of positions: a member of the initial board of governors for the Nova Scotia Sport Hall of Fame in 1977, a member of the Nova Scotia Boxing Authority, vice-president of the Nova Scotia Amateur Baseball Association, and the information officer for the 1987 Canada Winter Games held in Cape Breton. MacIsaac passed away in 1989.
