Taken in context, Beyaks comments on the residential schools are perhaps a statement of the truth. While nobody supports (and only a few idiots would deny) the fact that there were some terrible things done in some (perhaps many) of the residential schools it would be a injustice to label everybody who worked in any such an institution with these crimes. 
It seems extremely unlikely that everybody who worked in these institutions was an uncaring racist who enjoyed beating small children. That some of them cared is evidenced by the many well educated and adjusted students who were at these schools. 
Most Canadians would agree that we do need to find a long term solution to the fact that our indigenous citizens still do not have the same assets and opportunities as the rest of us. Beyak herself appears to acknowledge this although her idea to provide a one time payment may be naive. 
I can find nothing in her remarks that could label her as a racist.
