A part of The Canadian Experience series of CBC documentaries, Talking Canadian was aired in 2004. It takes an often-amusing look at the Canadian accent, intonation and vocabulary, how Canadians speak today, and how they will talk in the future.
I was unable to find the documentary with subtitles, although the YouTube CC subtitles may help a little bit. Anyway, The Canadian Experience can help us to understand how English is spoken in this part of the world and their well-deserved reputation as the most accessible accent for English language learners.
