Chart Question: Toronto class "B"

[Soku39]

I noticed something today that I've never noticed. A stuent pointed out that Toronto's very inner ring only went down to 2500 feet, the ring right outside of that goes even further down than that to 1700. Now I know Canada does not have the same airspace classifciations as the US, but why on earth wuold the inner ring not be down to the surface, let alone actually being higher than the ring outside it. So if anyone has any rhyme or reason as to why this is, I would greatly appreciate an explanation.

It appears that below 2,500 in the inner ring is Class D.

It's the same here in Brazil and in other ICAO places, class Bravo is not to the ground, in this case the actual airport is D, in Brazil we just call it terminal airspace, usually it's where you talk to the tower, outside that, in the Bravo it's app.

Alright that makes sense. So it's really like 2500' to the ground. I guess I'm just used to the FAA depiction where they take B to the surface. Seems like chart semantics mostly.

Yeah looks like it is a different method of achieving the same thing. In the US the tower "owns" a portion of the class B which in effect is the class D. There it appears they differentiate between the 2.

And when you fly in there in something fast, remember 10, 200, 3000. 10 miles away, 200 KIAS, 3000 ft. Within 10 miles of the field under 3000 AGL, you are limited to 200 kts. Canadian class B doesn't mean you can go 250 like in the States.
