 The log-filled Ottawa River, as viewed from Hull, appeared on the back of the Canadian one-dollar bill until it was replaced by a dollar coin (the "loonie") in 1987, and the very last of the dwindling activity of the draveurs on these rivers ended a few years later.Ottawa was founded later, as the terminus of the Rideau Canal built under the command of LCol.John By as part of fortifications and defences constructed after the War of 1812.
