Whitehorse is not undesirable, it's located in a beautiful valley and has a fairly mild climate

I think you have a somewhat skewed idea of mild climate, tbh, because the Territories aren't what I think most people consider mild

I'm also not talking about necessarily the scenery. What is the nightlife like? The job market? The restaurants?

Also being that far north you have the problem of the length of days and nights being very skewed throughout the year
