Fair enough, I havent found any cases on CanLII specifically on this matter. Almost all cases were obvious.
By 'almost all cases were obvious', do you mean they fit the rough description I gave above? Or something else?
I mean, to support this point differently: the Charter of Rights is pretty clear - "
Rights to move and gain livelihood
- (2) Every citizen of Canada and every person who has the status of a permanent resident of Canada has the right:
to move to and take up residence in any province; and
to pursue the gaining of a livelihood in any province"
Note it applies to PRs. There are some limitations on these rights but none that obviously apply to PRs under provincial programs.
Now, this isn't a 'lock' - but if IRCC or the province wished to pursue, they'd probably have to do so as misrepresentation, and they are aware that cases on this would be wide open to challenges based on some pretty common principles in law: first, that a charter right shouldn't be overridden lightly; second, that an open-ended "I intend to settle in a province" is not a contract and 'intent' can change based on circumstances; and three, that a statement of intent with vague, open-ended (i.e. no specific dates) terms cannot be considered perpetually binding (or put differently, it's simply not a contract that you can be 'held' to.)
I'm not a lawyer and you have to look at what engagements you made when you 'signed up.' But I tihnk there's close to zero chance that you could be held to it beyond one year (or have immigration repercussions after that period). Of course, only going by what you've shared and assuming you've not omitted anything critical.
