On 31 October 1780 the brig-sloop HMS "Ontario" was foundered during a violent storm and was sunk east of Fort Niagara on Lake Ontario with the loss of 80 lives including one officer, 34 other ranks, four women and five children from the regiment. The resting site of HMS "Ontario" remained a mystery until 2008 when the nearly pristine brig "was discovered resting partially on its side, with two masts extending more than 20 metres above the lake bottom", in approximately 150 meters of water "off the southern shore".
