Henry Atlookan was 32 when he set out on a solo canoe trip from Whiteclay Lake toward Armstrong in northern Ontario in 1968. He is described as slender, with black hair and brown eyes. His intended route covered about 55 kilometers through Crownland that later became Wabakimi Provincial Park, an area of interconnected lakes, rivers and dense boreal forest.

The last potential sighting was on June 25, 1968, when a man believed to be Henry was seen in a store in Armstrong. After that day nothing of his canoe or personal belongings was ever found, and no confirmed trace of him has emerged. With no physical evidence, the circumstances of his disappearance remain unknown.

Does anyone who lived in the Armstrong area in 1968 or who travelled that route remember seeing Henry or his canoe?
