<canadian-pedantic>A kayak is longer and thinner and lower to the water and is often covered. A kayak is typically paddled using a double ended paddle. In Canada, the boat in the article is a kayak; I don't think anyone here would call that a canoe. A canoe is deeper, wider and fatter (like some Canadians perhaps ;). A canoe can transport a lot of cargo but is also light enough to carry across portages. Many years ago native people and fur traders could travel entirely across Canada in a canoe. Some people still attempt this feat.
In other parts of the world the boat in the article might be considered a canoe, but I would say not in Canada. </canadian-pedantic>
