The text of the agreement says:
Canada shall grant temporary entry and provide a work permit or work authorisation to [these workers]...and will not: (a) require labour certification tests or other procedures of similar intent as a condition for temporary entry; or (b) impose or maintain any numerical restriction relating to temporary entry.
I think that's pretty clear in terms of Canada's right to impose any kind of test on the qualification of workers coming into Canada. Wouldn't you agree, Minister?
