I wish we still had ethanol free in Canada. But I guess that's not my choice to make...
However I don't think the ethanol has caused me problems. (though I have definitely seen it's green evidence in float bowls)
I do believe marine/marked/not taxed fuel with ethanol has caused me problems but I might be crazy, those problems disappeared when I stopped using the marked fuel.
Your strategy of putting the Husq premix before storage is a good idea, but probably overkill if you have ethanol free available. Dumping the fuel out and running the saw out of gas is another good strategy that I use maybe 20% of the time. 80% of the time I do nothing special and don't seem to have any issues. (probably 20 small engines around the yard)
Ethanol in gas is a provincial decision. In SK the Coop refinery does not add ethanol in their premium fuel, I’m guessing BC has mandated ethanol must be added. If you have Coop gas stations in BC it might be worth investigating.

I have not personally tested all our fuel. I have at times asked gas station attendants about it but have been met with blank stares or worse. The best I can do is go to the internet which says:
"The government of Canada currently requires that gasoline at the pump contains an average of five per cent ethanol. Some provinces require a higher percentage and gasoline may contain up to 10% of ethanol depending on where you are in Canada."
If a local fuel source had ethanol free, I would certainly use it for my small engines.

Don’t store it with fuel. I just use pump gas. I guess you could convince me to fill up with ethanol free for the last tank of the day.
