Does anyone in this forum know if class C in Canada is equivalent to class B
in the USA? I have been told that the USA does not follow ICAO conventions
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?)

Canada doesn't follow ICAO conventions all the time either - our "Class F"
Restricted/Advisory airspace isn't what the ICAO means by Class F.

Countries don't *have* to follow all the ICAO conventions - they can pick
and choose, and then register their differences w/ the ICAO.
