Since your brother has a child, he is no longer a dependent of your parents either if parent sponsorship was an option.
Having a child does not mean a person is no longer a dependent of their parents. Provided they fit into Type A, B or C, they are still considered a dependent even if they have a child.
Type A - The dependant is under the age of 22 and is single (not married and not in a common-law relationship).
Type B - The dependant has been continuously enrolled in and in attendance as a full‑time student at a post-secondary institution accredited by the relevant government authority and has depended substantially on the financial support of a parent either:
since before the age of 22, or
since marrying or entering into a common-law relationship (if it happened before the age of 22).
Type C - The dependant is 22 years of age or older, has depended substantially on the financial support of a parent since before the age of 22, and is unable to provide for himself or herself because of a medical condition.
