Desjardins Canal, Urquhart Butterfly Park, 128 King Street East, Dundas, ON

Excerpt from Wikipedia:

 

The Desjardins Canal, named after its promoter Pierre Desjardins, was built to give Dundas, Ontario, easier access to Lake Ontario and the Great Lakes system of North America. Although a technological achievement and a short term commercial success, the canal was soon eclipsed by the railway, and Dundas by neighbouring Hamilton.
