Mixed. A lot of Canadians support their aims. For example, facing public backlash, the provincial government in Quebec just scrapped plans to charge an extra tax to unvaccinated people for health care. I think as a general rule, most Canadians are starting to feel that after nearly two years, enough is enough.
On the other hand, a lot also think the convoy are just right-wing anti-vax reactionaries. Typical with the press, they're focusing on the relatively few distasteful things the mob have done (with a crowd of something over 50,000, apparently, they're inevitable) and blowing it out of proportion. For example, it's been reported that a landmark statue near Parliament Hill has been "defaced." Someone draped a flag on it. Technically that might fit the definition of defacement, but the word seems rather carefully chosen to imply some sort of physical damage to the statue, which has not happened. On Saturday, a few protesters parked, illegally, at the national War Memorial. They were towed. Some American news networks I've heard have reported this stuff as a mob of thousands roaming around downtown Ottawa desecrating national monuments, instead of a handful of ignoramuses.
It's been four days, and I think some of the downtown businesses are starting to suffer. This protest started just as the province started easing restrictions that closed up all the restaurants, for example. The largest shopping centre in the city (which is about a block from the Hill) has been closed since Saturday and announced today that they will remain closed until Sunday, because there are too many protesters coming in, flouting the rules, and refusing to mask up while they're in the building. The roads are closed in several blocks of the downtown core, disrupting traffic and public transit. The general feeling downtown, I think, is that the truckers are starting to overstay their welcome.
I can see that point of view, but as long as they behave within the law, legal residents of Canada have a constitutional right to be here and to express themselves.
