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.
When you enable banks to cease your account without legislation or due process that is marshal law. You can't do anything without money unless you have something to trade.
