[edit] Does Class B airspace exist everywhere in Canada?

Regarding the statement "Class B airspace exists between 12,500 ft. and 18,000 ft. everywhere in Canada", though this is a commonly held belief, I'm not sure it's true. If you look at the definition of Class B in the either the AIM or the DAH, you get this: "all low level controlled airspace above 12,500´ ASL or from the MEA, whichever is higher, to below 18,000´ ASL".

Note the qualifier "controlled". If you look at, say, the Calgary VNC, you'll see that outside of a 60 NM radius from Calgary, there is plenty of uncontrolled airspace. See the area to the north-east over Coronation, for example. This leads me to believe that such airspace, even up at, say, 15,000´ ASL, would be Class G, not Class B.

Anyone out there in authority care to comment?
