Does anyone here know if Canada's class C is equivalent to the USA's
class B? A Canadian has told me this is so and that the USA does not
follow ICAO convention. Is this true?

It is true. The Canadian class C requires a clearance to enter, just like
the US class B. They also have a 30NM mode C veil. They are depicted as a
class B (blue lines) on the US sectional charts, although the airport
surface areas are shown as a class D.
