That's is true but if I move tomorrow to Ontario, I'll be paying taxes in Ontario starting August 2025 which is a prove that I reside in Ontario or at least moved.If you are factually/substantively living in Quebec, then you will have to continue paying the 'additional' taxes (adjust) in Quebec. Which will be admitting that you reside there.
And if you don't - you're not paying the taxes due in Quebec. And Quebec won't get the adjustment taxes they are due from Ontario, because you didn't declare it properly. (Yes, the provinces adjust between each other afterwards)
I have to submit the application before October so I have to make a move within August/Sept max.
