Note on the definition of sympathy. One can have sympathy for where someone’s coming from but completely disagree and be opposed to an action it inspires them to take.
From the Ipsos poll:”A sizeable minority of Canadians (37%) agree (16% strongly/21% somewhat) that while they might not say it publicly, they agree with a lot of what the truck protestors are fighting for”
You claimed that the survey showed that they "support" the protests. The question asked only if people "sympathize" with the "frustration" of the convoy. That is a very low barrier, easy yes, given that a strong majority of Canada is tired of mandates. Indeed, the question went so far as adding "may not support the protest" to specifically delimit.
Canadians are very against this protest. If they simply parked some trucks and hung some signs, whatever. Once they were blasting horns 24/7, and then when that didn't work (given that the overwhelming majority of "truckers" are not with their cause and continued working) blocking international borders, the Canadian public turned dramatically against this petulant outrage. Having a bunch of Americans cheering it on, financing it, and even trying to join in has made it a cause that most Canadians find outright treasonous now.
Having sympathy is a form of support. And even the latest polls say 1 in 5 Canadians "want the protestors" to stay. That's what? A few million Canadians?
Plenty of people are sympathetic if a starving man breaks into a store to steal some food. That isn't the same thing as being supportive of breaking and entering or theft.
In democracies, we tend to ignore things when they only get 20% support, and that's if nobody is actively being harmed.
I hope that the convoys are not only completely cut off from economic support, but also that the people driving those trucks are identified and prevented from ever crossing the border into the US. Truck driving is a decent job. Be a shame if some of them were forced to earn a living doing something else from now on.

This is a terrible understanding of Canada's system and the Charter of Rights and Freedoms (including the ones that Trudeau just suspended with the Emergencies Act).
It's not hard to understand how authoritarian systems come about - it's people like you who gladly support them as long as the enemy is someone you agree is bad.
And sympathy is a kind of support. I mean, you can have support without sympathy for the cause they are protesting?
22% said they should stay, so 1 out of 5 directly support it.
