I'm glad I live in a country where at least a small minority (let's use the 10% number) disagree with the curtailing of our constitutional rights instead of all 100% of us just going along with it. And you should be too.
and even if one were to presumptuously accept the/your suggestion 'constitutional rights' were/are being infringed, what's wrong with following the typical procedural approach to seek remedy per Section 24(1) - Remedies of the Canadian Charter of Rights and Freedoms?

...to actually listen to what they have to say...
of course there's no shortage of organizers claiming position/protesting authority to make demands! Like these from the, 'Freedom Convoy 2022' organizers; specifically:
=> The federal and provincial governments terminate the vaccine passports and all other obligatory vaccine contact tracing programs, or Inter-Canada passport systems.
=> Terminate Covid vaccine mandates and respect the rights of those who wish to remain unvaccinated.
=> Cease the divisive rhetoric attacking Canadians who disagree with government mandates.
=> Cease to limit debate through coercive measures with the goal of censoring those who have varying or incorrect opinions.
