Without looking up the specifics, by the time of the convoy, the vast majority of covid restrictions were gone. They liked to complain about vaccine passports, which Canada had, but by 2022 the vaccine passports were gone everywhere except the US border, by the request of the US government.

It started as a protest against vaccine passports but really turned into a ragefest against the establishment.
