During the winter, supplies can be shipped by rail to Churchill, so everything can be warehoused until it's ready to be shipped during the summer shipping season. Not sure if stuff could sent there using ice roads though, as sea ice is tricky. Harbour facilities would defintely have to be upgraded in Churchill though for storing fuel and other supplies.
Like I said, reverse Ice Road Truckers. The ships would be racing in the summer instead.
Spend now and save later.
