You are obviously being misled by this consultant. Enough people have already told you he is an idiot so I'm surprised that you have persisted with using him and have not gone to a real lawyer. With a removal order in play you have no other option- get a reputable lawyer to advise you and be prepared that your mother in law will have to leave Canada very soon. If she is deported things will get a whole lot more complicated for you.
You should ditch the consultant, get a legal opinion from someone qualified and reputable, and make arrangements for your mother in law to voluntarily leave Canada. And do this very quickly.
