Anticosti-class minesweeper

The Anticosti-class minesweepers were a class of minesweepers that served with the Canadian Forces from 1989–2000.

The class consisted of two former oil rig supply vessels, the Jean Tide and the Joyce Tide. They were acquired by Maritime Command (MARCOM) and commissioned in May 1989 with the Jean Tide becoming HMCS Anticosti (MSA 110) and the Joyce Tide becoming HMCS Moresby (MSA 112).

Prior to conversion to mine-sweeping training ships, HMCS Anticosti and HMCS Moresby deployed on initial ships' training exercises on the east coast of North America. Later, Anticosti played "orange force" to the USCG's "blue force" in and around the waters of the states of New York and New Jersey, USA. Anticosti also carried the flag on deployments to the west as far as Kingston, Ontario, to the east of St. John's, Newfoundland, and to Freeport, Bermuda in the south.

After conversion, the Anticosti class was used for minesweeping training in preparation for the Maritime Coastal Defence Vessel Project, what would later become the Kingston class of patrol vessels in the late 1990s.

When the Kingston class entered service, the Anticosti class had minesweeping equipment and armaments removed. Other modifications included the fitting of astern refuelling gear to Anticosti in 1995. Anticosti was also used in the East Coast MARCOT exercise as a minelayer on at least one occasion. Both ships had been decommissioned by 2000.
