Since Alaska is significantly larger, that factor of 20 is not
particularly relevant.

If you want to consider population density, Alaska has a density 7
times that of Yukon. This is a rather enormous difference.

Furthermore, gun availability may well be HIGHER in the Yukon.
(Centerwall does not have any data on gun ownership in Alaska and Yukon.)

Legal availability is certainly lower in the Yukon than in Alaska.

It is? What evidence do you have?
