The Canal system connected the Great Lakes
The Trent-Severn Waterway is a feat of human ingenuity which connects Lake Ontario and Lake Huron at Georgia Bay and Port Severn, respectfully. The canal was originally considered a military route, but in 1833, the first lock was built for a commercial venture.
However, despite constructing additional locks, the government eventually gave up on the idea of using the canal for military purposes. Instead, the canal was connected through toll roads, plank roads, and railways to satisfy business interests. This resulted in a 386-kilometre-long canal route that we know today as the Trent-Severn Waterway.
