Canada’s Rideau waterway linking Ottawa (the nation’s capital) with Kingston Ontario was built for military purposes but its role evolved dramatically in the years to follow. So did Canada, which did not exist as a nation until 1867.

The war was inconclusive with both sides declaring victory in what was mainly a series of skirmishes.
