This is a parody post, right? Like your claims are so absurd as to convince readers the government has overreached, yes?

> violating the highway traffic act

Show me the man, and I'll find you a crime. Seriously man, what the fuck is the "Highway Traffic Act."

> an injunction granted specifically against honking horns

Let's simply declare a benign activity that people do thousands of times per day in every city, illegal!

> this specific protest at this specific time

But also, you better not show up at similar protests at other times either

> provincial state of an emergency

Yep, the blanket "emergency declaration" that makes virtually everything we don't like, illegal

> joining an illegal activity

because we just declared whatever you are doing to be illegal

> anyone providing monetary support to said illegal activity may have their accounts frozen

so you don't have to be a protester to be engulfed by this, just offering $5 so someone can get a coffee means you could have your accounts frozen. Cast a wide net, indeed!

> It'll be up to the courts to decide after the fact

Yes, by judges who are appointed by Canada's federal government!
