Trudeau has invoked the Emergencies Act. This gives him the power to invoke the military but it isn't a given. He has even said that he is not invoking it.
Emergencies Act does NOT equal Martial Law.
BTW, I suspect the only reason he has NOT invoked the military is because they probably won't listen to him.
Some say the u.s. is not under martial law. But are we? Hmmm
Our national emergency is still on.
