Airline Airport Codes for some Canadian cities

I play on Twitter a lot. I love puzzles. Many times people refer to a city using the airline code name. I get so lost! I haven't memorized those!
Well, here are some, courtesy of World Airline Codes, who collects them.

Calgary, AB	YYC	Nanaimo, BC	YCD
Charlottetown, PE	YYG	North Bay, ON	YYB

Now, I know these planes aren't the biggies, but they're the ones I get the most photos of in cottage country!
