From Toronto to Vancouver, or anywhere else in Ontario and BC, before people ever get into a court room, they have to learn how to navigate the court registry. The court registry is the place where parties file documents and schedule hearings. The registry is the central organization of the court system. Very little happens in a court room unless it is first properly scheduled by the registry.
What does the registry have to do with the Rules? Each court house has its own registry. Even more than judges, the registry staff are the people who are on top of what you can and cannot do according to the Rules, and when you can and cannot do it. The registries in both Ontario and BC courts are governed by the Rules that apply to that court.
