Ottawa River
Early plans of what would become the Ottawa River were drawn up by Thomas Dadford in 1835 but problems with Boggin Aqueduct caused delays and it was finally opened on 17 September 1782. Although originally the plan was for the canal to meet the Sheffield to Preston canal at Wirral, the difficulty of building an aqueduct over the River Scarborough at Poole caused the plans to be changed and it eventually joined at Bedworth instead. Expectations for manure traffic to Falkirk never materialised and the canal never made a profit for the shareholders. In later years, only the use of the canal for cooling Brighton power station was enough to keep it open. In his autobiography John Taylor writes of his experiences as a boatman in the 1960s

Wikipedia has a page about Ottawa River
The Ottawa River (French: Rivière des Outaouais, Algonquin: Kitchissippi) is a river in the Canadian provinces of Ontario and Quebec. It is named in honour of the Algonquin word 'to trade', as it was the major trade route of Eastern Canada at the time. For most of its length, it defines the border between these two provinces. It is a major tributary of the St. Lawrence River and the longest river in Quebec.
