I am only a Canadian, and not a Canadian lawyer, but I don’t think it will be as simple for Yukon. The biggest reason I can think of is that Yukon is a territory, and not a province, and so has different constitutional standing. From the government webpage:
There is a clear constitutional distinction between provinces and territories. While provinces exercise constitutional powers in their own right, the territories exercise delegated powers under the authority of the Parliament of Canada.
I’m not saying it isn’t possible, just that the same legal maneuvers Quebec used may not be applicable.
They might, but I can’t say for certain. I didn’t mention it because, again, I’m not a Canadian lawyer, and the basic info on provinces vs territories was far more accessible.
