I am looking for such particular case only-You can search the forum for some examples. There are examples. The search function isn’t great on the forum so not going to spend my time trying to find the posts. It is pretty clear in the application instructions that a PR must be living in Canada to sponsor a spouse. Landing in Canada together has nothing to do with COPR being cancelled. Most are denied before getting COPR although I have seen a case where a COPR was cancelled after being issues after it was discovered that a spouse had been abroad. Why risk the application being refused? Also not follow the application instructions could lead to scrutiny of any future applications.
