I'm not aware of any programs that will allow that. What you seem to be referring to is the lonely Canadian program, which your father doesn't qualify for in order to bring his brother. His brother will get extra points under the Express Entry progam since he has family here, but that's about it in terms of benefit for immigration.
IF your father received PR through sponsorship then he has family and living relatives in Canada. He would not be able to sponsor his brother. Who sponsored your dad?
