Why? Well, in short, each province or territory in Canada is constitutionally responsible for legislation about public safety within their boundaries. Hence, time for parallel and separate reviews, then separate and additive fees, and then separate registrations, etc. are currently required. In this day and age, when ideas can flash around the globe at a key stroke, national CRN registration of designs (i.e. ideas) in Canada seems to be, well, quite awkward and glacial in December.
This is not to say that regulators do a bad job. On the contrary, they are needed, appreciated, and certainly do contribute to the safety of the populace by helping owners of equipment (users, manufacturers, distributors, etc.) meet safety requirements. Indeed, regulators are of particular im
