> Up to 365 of those can be accounted for while being a temporary resident (on a work or study visa) on a "1 day for 2 days" basis.

I think it's more like every day that you are physically present in Canada pre-PR counts as 0.5 days. There's no such thing as a "tourist" under Canadian immigration law: you get a temporary resident visa/status/permit for your temporary "tourist" visits.

I think the part-day test applies (if you arrive in Canada at 10PM, even though you were only present for 2 hours, it counts as a half day).
