Ok, so Im reviewing the CDA. I find some stuff clear, some not so. Maybe the more experienced pilots can help out.

Class A is easy. It is not specifically charted, but goes from FL180-FL600 inclusive (SCA) and FL230/FL270 in the NCA and ACA respectively.

Above Class A is Class E (from FL600 to the moon or 90 miles, or something weird)

Class B gives me a headache. Most people just say its low level controlled airspace from above 12,500' ASL, but I'm not so sure its always like this. The AIM says above 12,500'ASL or the MEA, whichever is higher up to, but not including 18,000'ASL.

So when they mention the MEA, I assume an Airway? What if there is no airway, no Class B?
Class B can also technically be a CZ and TCA.

Class C and D- Easy again. They are charted and are either TCA's or CZ.

Class E- Okay, this can be a lot of stuff. Control Zones without operating towers, TA's, CAE's, Low Level Airways

Class F- Easy too. Charted CYD/CYA/CYR

Class G- Not charted, but everything other than A,B,C,D,E and F

Anyone care to correct, fill in, etc that would be great.

PS: Im looking at CYLS (Lake Simcoe Regional in Ontario) Can somebody tell me the breakdown of airspace class from the surface to Class A?

Any airspace above 12.5 (and the MEA) that is controlled, is class B.

In other words, if it's an airway, above 12.5k (and the MEA) it becomes class B.

Currently there are no Class B control zones nor any other Class B below 12.5k in Canada.

People try to make stuff 'way too complicated.

There are three different kinds of airspace in Canada

1) airspace that you don't have to talk to
anyone, to enter

2) airspace that you have to talk to someone
to enter

3) airspace that you're not allowed in at any time
(e.g. Class F CYR).

This is really not very hard to comprehend, but
if you look at the list of TC Enforcements, #2 and
#3 are in the top five, which is incredible, given
how cheap a moving-map GPS is.

PS I lie like a rug. You can fly in #3 class F CYR (I
do it all the time) as long as you have the permission
of the controlling agency. Really, #3 is just #2.

Thanks for the replies so far.

I found a cool website that shows you airspace.

The weird thing is that it doesn't show too much Class B in Canada.

Also, if you pick an airway, it shows Class E from 2200 feet AGL to 17,999'ASL, but not Class B above 12.5. Is this wrong?

Thanks again!

interesting link thanks...

but it is incorrect with respect to the airway airspace. It is as photofly indicated above, above 12,500 (or MEA) to FL180 it will be Class B airspace, below that to 2200 AGL Class E and typically under that Class G
