The Second one is so long so I copied part of it, the last ones I don't copy are the charges 
Dear XX:
Per our conversation today, I’m pleased to provide you with the exact legislation in the Immigrant Refugee and Protection Act (IRPA) pertaining to the ability to sponsor a relative who has no family in Canada defined as a “spouse” (husband), a child (son or daughter), “a relative who is a child of that mother or father” (sibling, aunt or uncle), “a relative who is a child of a child of that mother or father” (grandchild, niece or nephew), “a mother or father of that mother or father (grandparent) or “a relative who is a child of the mother or father of that mother or father” (a cousin).
For a review of the exact phrasing of the regulation, you may consult Section R117(1)(h) of the Refugee Protection and Immigration Act – Regulations:
xxxxxxxxxxx(like the link PMM offered)
In short, it appears that your Aunty has absolutely NO FAMILY left in Canada – and that your relative is a “Citizen” or “permanent resident” of Canada –she’s certainly eligible to petition anyone outside Canada under the family sponsorship program. As of today, the program is available for submission.
