I am doing another labour relations course at George Brown, and the teacher, who is a highly respected labour relations professional, said that the Queens program is amazing. Because I live and work in Toronti, my first choice is here, but my prof is adamant that Queens has one of the best programs in Canada.
Both schools are top notch universities, and so I don't think there is a wrong choice. I went to Queens for my undergrad, and it is an amazing school and gorgeous campus.
Good luck everyone!
