The web is a massive change that lets media bypass the "gated communities" of past pre-internet media distribution. For example, instead of the CRTC regulating radio and television waves with CanCon, things like illegal downloading/streaming or music/films/TV shows and places like YouTube means the CRTC has absolutely no control over the media Canadians watch from those sources. This is indeed causing a turn away from the Canadian mass media content we all enjoyed in decades past.
Not sure you can get around this, other than making stricter copyright laws on internet ISP's on allowing certain illegal downloading/streaming or better enforcing these laws. I think certain protection is important.
