Canadian permanent residents and citizens can apply to sponsor their brothers/sisters who are under the age of 18 and who do not have a spouse or common-law partner. To sponsor the Canadian permanent resident and citizen must agree to:
1. financially and socially support the brother/sister for 10 years or until they reach the age of 25
You can also sponsor your brother/sisters who apply for a permanent residency. By doing so they can claim an additional 5 points which would help them qualify for a permanent residency application.
