I see a lot of posts like this, and this is straight up disinformation. I'm not assuming it's willful, since disinformation breeds disinformation, but here's my account as someone who lives here
and is glad Trudeau resigned.
The idea that it was a few days of honking then bouncy castles is nonsense. It was an extended occupation of the downtown of the capital. Endless trucks and other vehicles, many with their wheels removed, back-to-back fully blocking a large section of the downtown for weeks. Yes, honking – and loud truck air horns.
There really was chaos downtown, and not the hand-wringing "poop in the street in SF" type. And a lot of it did have right wing vibes. Examples: A well known café had its large window with a LGBTQ illustration smashed. There was while when emergency workers needed escort downtown because of racist abuse. (I was downtown, I heard and saw a ton myself.) Just incredibly dumb stuff: A soup kitchen was intimidated and raided.
And yes, it was financially supported by the "right", including a lot of American money.
Yes, there was a site with bouncy castles and kids playing, but that's obviously not a problem. There's protest in Ottawa all the time, and it's sometimes inconvenient, and that's life in the capital.
The last straw for me wasn't even the chaos in Ottawa, but the protest shutting down the Ambassador bridge in Windsor. That's really bad. Ontario's auto sector is huge, and the perceived reliability and predictability of the flow of intermediate goods across the border is everything to that sector. Interrupting it has an enormous immediate and ongoing economic impact. (I'm not sure where you get your information, but the bridge is also in Ontario.)
None of that is to say that the emergencies act was the right tool. My fairly uninformed impression is that there were tools short of the act that should have been used.
But it's frustrating seeing disinformation and revisioning like this stand. Please reconsider whatever news sources are providing you with this false information.
