Why a Lake Superior-Hudson Bay canal struggles to pay

Would a canal from Lake Superior toward Hudson Bay create a useful new northern route?

It could be built with enough money, but geography, ice, locks, and existing railways make it very hard to justify economically.

The discussion examines whether mineral and grain traffic could justify cutting a route of roughly 310 miles from Lake Superior toward Hudson Bay. There is no major river to follow, the terrain is rugged, Lake Superior sits hundreds of feet above sea level, and seasonal ice would require another expensive system to manage. Existing railways already reach much of the region, while most refining and onward commerce lies to the south. Even a technically feasible canal would therefore duplicate transport capacity without collecting enough intermediate traffic to repay its locks, cutting, and winter operations. Expanding heavy rail is the more credible answer.
