The northern territories, and Nunavut in particular, have some pretty unique supply issues. They all suffer from a lack of infrastructure, and Nunavut especially has all those Arctic islands which are only accessible by sea during the short summer and by air otherwise, or only by air period for some of the communities located more towards the interior where the ice pack never fully goes away. This results in some very high food prices.

This idea is an attempt to increase shipping volume to the north in an affordable way. Whether it’s actually workable or a harebrained scheme I’m not qualified to say, though.
