Which document defines the Canadian "amateur radio service"?

The Radiocommunication Regulations are where the specific definitions of various radio services, including the "amateur radio service," are legally established in Canada. It is important to understand the hierarchy of Canadian radio law. The Radiocommunication Act is the overarching parliamentary law that grants authority, but it does not get into the detailed definitions of individual services. The Regulations contain those specific definitions, while the "Standards" document dictates the everyday operating rules for amateurs.
