Thank you CEC2013Ray.CEC2013RAY said:You and your wife's PR application will be delayed a few months if you notify them about the marriage before your PR application finalizes. On the other hand, if you notify after you become PR, it will take 1 year to 2.5 years depending on where you apply for family sponsorship.
So I would recommend to inform CIC now.
Any one else want to suggest anything else, would be appreciated.
