Good question. Thank you.
Let me bring two things forward.
Canada has a self-regulatory framework across the board. This is based on the Constitution and the way most of the provincial governments have decided to regulate their professions. Almost everywhere you will find self-regulation. This is a Canadian pride kind of thing.
In the case of other countries, most of them in the regulation industry are government regulated.
In other professions, self-regulation is not common everywhere outside of Canada. I'm not sure if that answers really the question.
