Apart from the quarantine requirements and possibly your point about free expression (though I'm not sure which incident that refers to and you provided no references), none of the rest of that list is under the purview of the federal government and is instead decided upon by the provinces.
In case you aren't familiar, Canadian provinces have near total control over most areas, with the federal government typically stepping in only in areas that were explicitly granted to it. The provinces, for instance, are responsible for all healthcare related decisions within their borders. The federal government licenses drugs and treatments as a centralized body for all provinces, though I believe here too the provinces can take some steps on their own. Provinces can equally ignore the charter rights of citizens for a set period of time by invoking a specific clause when passing legislation (it's been done several times recently). Provinces wholly own their mineral rights, including into the waters on their borders.
The point I am making with this explanation is that the issues the convoy began protesting (that truckers had to be vaccinated to cross the US/Canada border) made sense to protest federally. Once it was apparent the US had implemented the same rule (coming into effect before Canada, if I remember rightly), the protest became about other mandates. These other mandates are purely provincial jurisdiction and the federal government could only hope to convince the Premiers to do what they ask. The protest is misplaced in its entirety at this point, which is why there is no cohesive direction.
