Portage is a way by land around an interruption in a water route. Until the early 19th century most inhabitants of what is now Canada travelled mainly by water. Alexander Mackenzie and Simon Fraser demonstrated that it is possible, by portaging 100 times, to canoe from the St Lawrence to the Arctic or Pacific oceans.
