Hmmmm noted,since you guys are having a baby lots is going to change, and u should also know that there is always a way to beat around this if he is smart ,For example, Exception in cases of abuse or neglect Given concerns about the vulnerability of spouses in abusive relationships, the proposed condition would cease to apply in instances where there is evidence of abuse (that is, physical, sexual, psychological or financial) or neglect (failure to provide the necessaries of life). they are not just going to grab him and throw him away, I know of someone who was in an bad marriage, his wife was cheating on him and still she called CIC to revoke his papers, CIC looked into it very carefully, luckily the guy has some recording of the wife threatening to cancel his papers every time he question her of her cheating, The guy had job and was paying tax , and the wife was taking his money every time, whenever he speaks he threaten him , Did you know that he got divorced and CIC did not revoke his papers, he is still living in Canada happily. the wife is the one been worried now, because if the guy goes to get money from government the wife will pay . different cases different outcome. You never can tell what is going to happen .CIC is not just going to grab someone and throw them out of the country just because the wife called, its step by step, if it was during the processing of the application thats a different thing, but once landed its kinda 50-50 that they will revoke his PR, all he needs is a good lawyer just hope everything works out for you. i know some people just take advantage and get what they want and then disappear.
