Many full programs are closed captioned. When the show starts playing (after any advertisements) look for the CC button in the player controls to activate the captions.
Some types of content are not yet available with closed captioning, including most short form content, such as web-first, time sensitive news clips. Also, clips taken from full programs lose their captions in the editing process. For example, The National as a full program has captioning, but individual stories taken from the broadcast do not.
We understand that closed captioning is important to many Canadians and CBC is working hard toward the eventual provision of captions on all new content online.
