The Maritime Coastal Defence Vessel Project (MCDVP) was a procurement project undertaken by the Canadian Department of National Defence beginning in the mid-1980s to find a replacement to fill the minesweeper, coastal patrol and reserve training needs of the Canadian Forces, replacing the Anticosti and Bay-class minesweepers, Porte-class gate vessels and Royal Canadian Mounted Police coastal launches in those roles. After construction these vessels became known as the Royal Canadian Navy's Kingston-class maritime coastal defence vessels (MCDVs).
