The main instruments in the tool kit for promoting Canadian broadcasting policy are enunciated in the Broadcasting Act. The objectives are set there.
The CRTC is mandated under the act to regulate the system to achieve those objectives. You'll be hearing later on from the CRTC a little on how they do their thing. A big part of the tool kit of course is the Canadian Broadcasting Corporation, which is given a mandate to create and present Canadian programming. Those are the two main instruments that support Canadian programming.
