I've always wondered why there are no Control Zones in Canada designated as Class B. The CARs and the Designated Handbook have the provision for that in there, but how come airspace as busy as CYYZ or CYYC is not designated as Class B. South of the border, loads of airports like Seattle, JFK, etc. are all Class B, so how come there's none in Canada? Is there anything already in the works?

The rules surrounding classes B and C airspace differ between the US and Canada, so there's no direct comparison.

Please, the last thing we need or want is pilots campaigning for more restrictive airspace classifications than we have already.

LOL.. Sorry Photofly, I didn't mean to burden pilots with more restrictions. Just wanting to learn more, especially in relation to why there is a classification for Class B CZ but none exist in reality. That's all.

There are provisions to have it in the future but there is simply no need to restrict flying further at big airports yet.

In Canada, Class B starts at 12, 500 or above the MEA whichever is higher. At large airports we have TCAs and CAEs which extend into Class B airspace with most (if not all) large airport TCAs being Class C and requiring VFR aircraft to have ATC clearance to enter, and will often be provided with Terminal Radar Service. Pretty sure you need to fly CVFR in Class B though so adding Class B CZs would just make it that much more of a pain for general aviation. We just aren't that busy.

Class B in the States is not the same as Class B in Canada. In fact, with a few exceptions, Class B in the States is more or less in line with class C in Canada. Class C in the States is similar to Class D in Canada.

Therefore, our major airports in Canada, namely YYZ, YVR, YUL, YYC, YOW, etc which are all Class C, offer pretty much identical services and ask for the same requirements from pilots compared to the class B airports in the States.

The major difference between US Class B and Canadian Class C can be found in the Code of Federal Regulations (CFR) 61.95, restricting student pilots on a solo flight. There is no such requirement in Canada.

Also class B in Canada requires IFR/VFR separation. So 3nm or 1000ft.

That would be in Class B above 12,500. In a Class B CZ, you could use 500' vertically and target resolution provided the conditions are met in 383.2.

You are correct, my bad, I just assumed as in the US even above 12,500 they don't give IFR separation that it was our thing. Thanks!

the other big difference is class C in Canada requires a clearance where class C in the US doesn't (only radio contact). Class C in the US is pretty much Canada class D with a requirement for a mode C transponder, hence the reason for class B (requires a clearance).
