She was commissioned into the Department of Transport's Marine Service in 1960 using the prefix "Canadian Government Ship". She was transferred in 1962 into the newly created Canadian Coast Guard and served with distinction until being decommissioned in 1991, and replaced by the then-chartered (but later purchased) Terry Fox.

The John A. Macdonald was known to CCG personnel as "The Queen of the fleet", and is also considered by many to be the finest Canadian Icebreaker ever built. In 1969 she assisted the then-new CCGS Louis S. St-Laurent in rescuing the MT Manhattan during its unauthorized transit of the Northwest Passage. During the rescue, the John A. Macdonald broke her starboard propeller in heavy ice; the propeller is on display by the Dartmouth Ferry Terminal, Dartmouth, Nova Scotia. In 1987 she underwent an 8-month, $8-million refit, only to be decommissioned four years later. She was transferred from the CCG to Crown Assets and was renamed 1201. She was sold for scrap and towed from Halifax Harbour in November 1993 and was scrapped in the early months of 1994. Retrieved from "http://en.wikipedia.org/wiki/CCGS_John_A._Macdonald"
