Yes, certainly there were limitations on people's rights with the proclamation of the Emergencies Act, but I think it's important to take a step back and talk about what we are actually interpreting, which are the words under paragraph (c) of the definition of “threats to the security of Canada” in section 2 and then how that applies to the declaration of emergency.
That specific provision isn't giving somebody a right or taking their rights away. The typical rule in that context is not one that I think would have a lot of sway in either direction, because it's not that element that is either giving a right or taking it away.
I agree that it's the general context of the act, so you might want to consider that when you're thinking about the context of the act, which is to potentially deny people's liberties.
