Try to convince the sibling .. As posted above you will need several documents proving existence of this sibling plus the fact that this sibling actually LIVES in Canada... I doubt trying to convince IRCC with anything different will be much use since it adds 15 points which can make alot of differencePlease can I get some clarity, I applied for the express entry with my husband who indicated that the has a sibling in Canada, he actually does have a sibling but this sibling has refused to provide the necessary documents at the last possible moment, what can be done?
