Also, you may be able to sponsor your sibling (no matter where you live in Canada) if you meet the following criteria:
"Note: you can sponsor one relative regardless of age or relationship only if you do not have a living spouse or common-law partner, conjugal partner, a son or daughter, parent, grandparent, sibling, uncle, aunt, nephew or niece who could be sponsored as a member of the family class, and you do not have any relative who is a Canadian citizen or a permanent resident or registered as an Indian under the Indian Act."
