ELI5: Why do so few people live in the Canadian Territories like the Yukon but Alaska has a much larger population with similar climate and geography?

Alaska population is 741,894 but Yukon right beside it has the lowest population out of any Canadian territory with only about 33,000. Why might Yukon have such a harder time attracting settlers?

It is actually warmer in Alaska as it is coastal. Being coastal also means settling it easier to travel as you can use boats, and sea planes. Being inland means you have to build infrastructure like roads, airstrips, railroads for modern travel, or like horses and pack mules.
