Canadian citizens and permanent residents of Canada, 18 years of age or older, may sponsor family members who want to become permanent residents of Canada.
When you sponsor a relative to become a permanent resident of Canada, you must promise to support that person and their dependants financially. Therefore, you have to meet certain income requirements.
If you have previously sponsored relatives who later had to turn to the Canadian government for financial assistance, while you were responsible for them, then you may not be allowed to support another relative.
Sponsorship is a big commitment, so you must be in a position to support that person financially, if they cannot support themselves, for a period up to 10 years, after they become permanent residents.
After that they are considered to be on their own.
Individuals living in Canada cannot, on their own, sponsor those they are not related to, for immigration to Canada. Sponsorship by individuals can only be done by relatives who are Canadian Citizens living and working in Canada.
For more information on sponsoring spouses and dependent children see:
Sponsoring Your Family
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.For more detail see the government website: Eligible Relatives - Who Can Apply?
There is another route to enter Canada, which French speakers and others may want to look into.
It is through the French-speaking province of Quebec which has its own rules and regulations.
You don't need to pay anyone to get you into Canada. Things don't work that way in Canada. It's all done by the legal route. Always be honest and straight with the government of Canada. Go by the regulations. Watch this video of what happened to this family.Becoming Canadian: Combatting Immigration Fraud
