Expo 86 was a world's fair in two parts. Most of the pavilions were located on the main site along the shores of False Creek, but the host nation had its pavilion quite a distance away. The Canada Pavilion was designed to serve as a convention center and cruise ship terminal after the fair ended, making it necessary to split if from the rest of Expo in order to secure funding. The two sites were linked by the new SkyTrain system, making it relatively easy for visitors to travel between the two.
Here's a view inside the Great Hall, the main exhibit area at the Canada Pavilion. In the center was a Haida Indian war canoe on loan from the Canadian Museum of Civilization in Ottawa.
