The death of Tom Thomson, the Canadian painter, occurred on 8 July 1917, on Canoe Lake in Algonquin Provincial Park in Nipissing District, Ontario, Canada. After Thomson drowned in the water, his upturned canoe was discovered later that afternoon and his body eight days later. Many theories regarding Thomson's death—including that he was murdered or committed suicide—have become popular in the years since his death, though these ideas lack any substantiation.
