I'd say that the suspension of due process started long before those protests began, back when the various levels of government started imposing forced lockdowns, forced masking, forced injections, travel bans, and curfews, among the other violations of the most fundamental of rights and liberties.

We should also keep in mind that the majority of citizens were not in favour of such actions. If the Canadian public had widely supported such measures, then they would have been self-imposed, and just voluntarily happened. The governments wouldn't have had to resort to mandates and other forceful methods like they did.
