Service history

The two ships were constructed by Allied Shipbuilders, Allied Shipbuilders Ltd. of Vancouver, British Columbia, Vancouver and named ''Joyce Tide'' and ''Jean Tide''. After completion ''Jean Tide'' served as an oil rig logistics support vessel for International Offshore Service of Liberia. In 1975 she was sold to Tidewater (marine services), Tidewater Marine. ''Jean Tide'' remained with this company until her sale in 1988. As part of the plan for the Naval Reserve to take over minesweeping and coastal operations, MARCOM began its effort to provide ships for training. MARCOM acquired two ships in March 1988. The ships were handed over for conversion by Fenco MacLaren Incorporated (later SNC-Lavalin Defence Programs Inc.) at Halifax, Nova Scotia and Ship commissioning, commissioned. ''Anticosti'' (formerly ''Jean Tide'') was commissioned on 7 May 1989 with Hull classification symbol (Canada), hull number MSA 110. ''Moresby'' (formerly ''Joyce Tide'') entered service on 1 January 1990 with the hull number MSA 112. The vessels sailed to Marystown, Marystown, Newfoundland for conversion. In April 1990 they had their mechanical sweep gear and sonar fitted. ''Anticosti'' was assigned to Maritime Forces Atlantic (MARLANT) as a minesweeping training vessel in preparation for the Maritime Coastal Defence Vessel Project (MCDV), which would become the ''Kingston'' class in the late 1990s. ''Anticosti'' was deployed by MARLANT in the annual MARCOT exercises as a minelayer. In March 1997, ''Moresby'' transferred to CFB Esquimalt. During the investigation into the Swissair Flight 111 crash in September 1998, ''Anticosti'' was among the Maritime Command vessels that responded to the crash site. She among the many ships scoured the sea looking for the aircraft's Flight recorder, black box as part of Operation "Persistence". In March 1999, ''Anticosti'' sailed with ''Kingston''-class vessels and to the Baltic Sea to participate in the NATO naval exercise "Blue Game". After the ''Kingston'' class entered service, the ''Anticosti'' class was identified as surplus and ''Moresby'' Ship commissioning#Ship decommissioning, paid off on 10 March 2000.
