• • Canada is the second largest nation in the world in terms of land area, following Russia (9,984,670 square kilometres and 17,075,000 square kilometres respectively). It is one of very few countries to have marine borders with 3 oceans: the Arctic to the north, the Pacific to the west, and the Atlantic to the east.

• • Canada has the longest coastline in the world. Hudson Bay, James Bay and marine islands all contribute to the length of its coastline.

• • Baffin Island, with an area of 507 451 square kilometres, is Canada’s largest island.

• • Eureka on Ellesmere Island (Nunavut) has the lowest tides in Canada. Their average height is less than 0,1 m.
