but my uncle Canadian passport doesn't have his parents nameAsivad Anac said:Check that here ---> http://www.cic.gc.ca/english/immigrate/skilled/apply-factors.asp
All of those documents would help as supporting evidence but the primary relationship document has to be the passports where you show their parent is the same as your father's parent.
Check 'Proof of relationship to relative' here ---> http://www.cic.gc.ca/english/resources/tools/perm/express/intake-complete.asp
I have asked my uncle to make one affidavit and notarized it from Canadian lawyer in which details of me my father and my uncle will be their saying how are we related to each other.
Will that be fine for proof of relation ship
Regarding his address in Canada I can take his bank statements or letter from his bank which states his address in Canada.
