You can't unless you are single, never married, have no children, your parents and grandparents are deceased, you don't have an Aunt/Uncle/Brother/Sister/Niece/Nephew in Canada.
And the brother would also have to be single and have no children. This is the clause in the federal family sponsorship program that says you can sponsor 'one other' relative if you have no family in Canada and no family elsewhere that you could sponsor. I looked into it with my brother and I was told that because our parents are alive, even though they are not interested in immigrating, that I could not sponsor my brother and even if our parents were dead, I still couldn't sponsor him under the federal system because he is married.
Under the provincial nominee programs, if you are living in AB, SK or MB, you could sponsor your brother and his family through the provincial program family stream as long as you and they meet other requirements, financially etc.
