The humiliation stung, and it planted a seed: Canada would build its own canal. Twenty-five years later, in 1895, the Sault Ste. Marie Canal opened on the Ontario shore -- not just a functional lock, but the largest and first electrically operated lock in the world. That story of defiance runs through this National Historic Site like the river current itself.
