CA-K1561History

Early science in Canada’s North, 1768 to about 1810

In 1768 the Hudson’s Bay Company sent two British astronomers to Prince of Wales Fort, on Hudson Bay, to observe the 1769 transit of Venus. It began more than forty years of HBC cooperation with the Royal Society of London in astronomy, meteorology, cartography and natural history in the North, with Indigenous collaborators sharing their deep knowledge of the land, plants and animals.
