I'd fully expect gay ops/false flags from the cops. The media and government reaction already demonstrates that this isn't an "approved" cause like the jogger lotteries. They'll need to come up with an excuse to arrest the dissidents and no government is against setting up its own citizens to do that.
I think this being a union strike with grassroots truckers this can go one of several ways.
1. Incompetence reigns nothing really happens and the protests die down as universal incompetence on both sides keeps things from going anywhere.
(They both play it safe and it's a short detante where the protesters back down. Ie it's celebratory but we all go back to work. Points are made publicly but nothing really happens.)
2. Full retard acceleration mode and crackdown on the protests are violent.
So we have multiple scenarios from there.
A - Let's say the protesters act to a brick being thrown at a window and it spirals down from there. Which riot police treat that crowd with an iron fist.
B - perhaps the police are encouraged to create altercations so they can tear gas and or beat the masses.
C - someone gets killed and the police lose control.
D - all of the above. (This usually backfires band grows support but if you crackdown hard enough you can stop it.)
(Not unlikely)
3. the protesters are given a win but it doesn't effect the system. Perhaps sacking Trudeau to save the gravy train.
(Very plausible)
4. Nothing happens as it all fizzles out. Protesters (Likely)
5. Protesters win the sentiment shows the tide. They follow England's route and signal the end of lockdowns and mask mandates. Basically the protesters are given a day, democracy actually works and within a few years the system destroys the movement.
Rare chance encounter
If number 2 goes down the most exceptional route. I think there is a chance that Canada becomes the first western country to have the civil conflict. This in turn could be the spillover conflict that brings the US to it's knees. But hey all the progressive shitlibs saying trump brought down America can be esoterically leafed by an incompetent Canadian causing a civil conflict.
