Yes.
I mean, ultimately, I think it's a question of what Parliament intended. Parliament can intend a broad delegation of authority to, say, the Human Rights Tribunal. It's perfectly legitimate. I'm not one of the people who would deny the legitimacy of administrative law writ large.
That said, there are trade-offs involved. If you're going to delegate to regulation-making bodies or administrative decision-makers, then you are, necessarily, undercutting the sort of representative nature of the legislative process. For example, going back to the Canada research chairs program, this is a decision that was made with no public consultation and turned out to be quite controversial.
The public wasn't even aware of this. In fact, I don't think most people know how this settlement came about at all. They're not even aware of the case. That's the issue with these kinds of measures.
