They don't need the military to put this down.
Feds will just get ahold of the list of signatures and threaten the people who signed with freeze/seizure of assets. They will dress it up as the penalty for 'sedition'. Why bother with bullets when they can just de-bank people? They already did a dry run of this at the convoy, you don't think Carney won't pull that trick again? All he has to do is his 'Elbows Up' routine and 80% of this stupid nation will be eating out of his hand (including millions of Albertans)
Laws are just words on paper, they can be (and are often) ignored at will. (See the Charter of Rights and Freedoms)
You can't use the system they created to vote your way to freedom. When the Americans wanted independence, they needed an army (and a war) to make that happen.
Most Albertans that I know haven't even boycotted Tim Hortons yet, so I think the sacrifice required is a long way off.
