Yes, and really, the mandates of the various commissions--federal, provincial, and territorial--are based on the constitutional powers of each. The federal commission has those powers the federal government has, so as the chief commissioner indicated at the outset, we cover all federal departments and agencies and federally regulated employers, whereas the provinces have jurisdiction within those provinces. If it doesn't fall to the federal government, it falls to the provincial.
There are some issues that might occur on a first nations community that would fall within provincial jurisdiction--for example, employment law--but they would not also fall to us. So there is no concurrent jurisdiction, but there is sometimes uncertainty as to where it lies.
The chief commissioner referenced CASHRA. There is a working group of lawyers studying the very issue of jurisdiction in the first nations context--the aboriginal context, more broadly speaking--to know which side it would fall on.
