No, Trudeau should never have met with them. I'm no Trudeau fan, but there was zero value in ever meeting with this group. They should have been swept up the moment they broke the first law.
"like suspending some restrictions conditional to hospital utilization"
Like almost everyone who has takes on this here (including DHH), you seem to know perilously little about the actual situation, yet you've got a lot of takes. The vast majority of mandates are provincial, for instance, not federal, just as health systems are managed at the provincial level. Ontario (the province that Ottawa is in), actually has a conservative leader, but the so-called "truckers" didn't target him at all, and their minimal foray into Toronto was immediately squashed by a much more capable police force. Nor did they do much about any other premier. Because it had little to do with mandates. These people simply don't accept democracy. They don't like Trudeau, therefore he's got to go. I mean, they literally said it over and over again. That's cool, but we just had an election so they can take their mini insurrection and go home again.
