Service history.
The icebreaker was constructed by Halifax Shipyard at Halifax, Nova Scotia with the yard number 5. The vessel was completed in August 1930 and named for Nathan B. McLean, a government official who led an expedition to Hudson Bay in 1927. "N.B. McLean" entered service with the Department of Transport's Marine Service and made annual trips to Hudson Bay and the Arctic Ocean from 1930 to 1970. Due to the Great Depression, no major icebreakers were added to the government fleet and "N.B. McLean" remained the most powerful icebreaker in Canada's fleet until 1950.
In 1962, all Marine Service icebreakers were transferred to the newly created Canadian Coast Guard. In the 1960s a flight deck and hangar were added to the stern of the ship. "N.B. McLean" made her final voyage to the Arctic in 1970 and was used on the St. Lawrence River and in the Gulf of St. Lawrence until being taken out of service in 1979. Following her decommissioning, efforts to turn the vessel into a museum ship at Quebec City, Quebec failed and the vessel was sold for scrap in 1988. The vessel was taken to Kaoshiung, Taiwan and arrived on 20 February 1989 to be broken up. The vessel was replaced by .
