Does anyone in this forum know if class C in Canada is equivalent to
class B

and is therefore wrong? Can anyone here credit or discredit this
statement?

In practice, Canadian C more or less equals US B; they're both used for
terminal areas around major airports. Canadian B is (AFAIK) only used from
12,500ft-17999ft.

(I have heard that Toronto/Pearson uses actual Class B down to the surface
for their control zone, but I live on the far side of the country and
haven't bothered confirming this. Anyone know if it's done this way?)



No, Toronto/Pearson is a standard upside-down cake, considered class C,
topped at 12.5.

Class B in Canada is only that bit from 12.5 to 18.0 along airways and other
geographical areas where it is considered "controlled" and hence Class B...
