Soft-landing and the new requirements

The new requirements for approved-COPR to enter Canada is “be coming to Canada to settle permanently (you cannot come to Canada and leave to go live in another country, even if it’s temporary)”

The “leave to go live in another country” part: Is it leave ‘immediately’? Or never leave forever? Or not leave until some X months?

If we come to Canada now, work for 3 months from Canada, leave, and then not come back for another 2 years, please let me know if you can foresee potential issues that can come up later on?
