in my opinion....the best options is to stick to what you declare in your previous application. less background check???
No, the BEST option is to tell the complete truth. PR applications receive greater scrutiny AND this is an opportunity for the OP to correct everything that was wrong with the previous application. If CIC finds out on their own, the OP is risking misrepresentation which would be stupid because it is NOT that big of a deal to correct it.
