Known as "Canada's greatest seaman," Joseph-Elzéar Bernier (a Fellow of The Royal Canadian Geographical Society) led a series of expeditions through the Arctic Islands and Hudson Strait between 1906 and 1910 to assert Canadian sovereignty. He and his crew placed cairns on high points throughout the Arctic to declare them officially part of Canada.
