Do English Canadians in fact make the best ESL teachers?

They certainly have access to a solid variety of British and American texts while growing up. 

Indeed, if you grow up watching a lot of television and movies in Canada, you'll likely become enamoured with many an American tale, while falling for several British narratives along the way. 

The same logic applies if you search out different American and British books simultaneously.

You'll have to in school.

By the age of 20, if you've been avidly consuming British and American literature, television, film, and music, you may then possess an instinctual understanding of British and American English, which can help you answer many an international question, regarding all things ESL Anglo.

I don't know if Australian, New Zealand, South African, East Indian, American, British, or Irish culture are as inundated with American media as Canadian culture is, and if Anglos hailing from those realms have access to the limitless wealth of American wit Canadians consume on a daily basis. 

But don't let the onslaught of American media distract you. 

Remember to consume as much Canadian media as you can as well. 

I taught myself when I was very young to give Canadian television and film a chance, thanks to a massive onslaught of SCTV reruns, and Kids in the Hall, but if you take the time to search for it, I guarantee Anglo-Canadian art doesn't disappoint. 

The Beaverton is quite good for instance. 

Australia and the other Anglo realms, good too.

Unparalleled access that helps you prepare for international and Québecois media later in life.

Which can start many a conversation in class.

Perhaps by making a poetic comparison.

Don't forget Rush.

Or Picnicface.

Boom.
