visiting_canada said:rjessome, I understand what you mean. However, this might be the case only for people who ACTUALLY got married after the PR visa was issued.
In my case, I was married 3 months ago, and I got my passport with PR visa today. If I inform the CIC now, they migh reject my case all together.
I know its my fault, but please suggest.
They will be annoyed but they will not refuse you based on this. The only reason they would refuse you would be if your wife was inadmissible for medical, criminal or security concerns. This is the ONLY thing you can do. It will delay your landing and cost you some money with medicals and application fees but if you don't do this, you will not be able to sponsor your wife and you are putting your own PR in jeopardy.
Stop trying to find a way to lie to them. You have a legal way to do this.
