I’d suggest you’re watching the wrong podcasts.
I live in Alberta and I don’t believe there is nearly that much support for separation, The real numbers seem to be in the low to mid 20% range.
Those who are separatist will likely destroy their own cause by looking for an early vote. A project like this is something that takes years of planning, with a well developed and thorough public relations strateg to build support in advance of a vote.
Many Albertans conflate separatism with MAGA, and that will hurt the movement in the near term. Promoters will have to “separate” (pun intended) their movement from MAGA if they hope to get any real traction. While there are some Albertans who support joining the US (and the media certainly seek them out), they are a very small number.
This is not to suggest that a majority of Albertans are happy with Canada at the moment. Most Albertans who are fed up with Canada, though, are just looking for a better deal from Confederation, not becoming an appendage to Montana. (Here’s a quiz: what is the population of the City of Calgary and how does it compare to the population of the State of Montana, which abuts Alberta to the south?)
Go too soon and you will fail, without a doubt.
