You've phrased this as a declaratory statement, but then you fall back on the fact that the entire thing is heresay from your employer.
The whole notion that "Candian courts value X over Y" falls into the "carefully guess the will of the judge" category; remember that any precedent can be overturned whenever a judge feels it's appropriate. Judges just aren't predictable: they can rule how they feel is appropriate, outside of external influences. That's good in some cases, bad in others. One of the ways that it's bad is lack of predictablilty: the notion of precedent mitigates, but does not solve, this problem.
Moreover, it's quite possible your employer's opinions of the Canadian courts are wrong. He does, after all, have a vested interest in getting you to divulge information about past workplaces: and little to lose until you leave. See if he changes his tune during the exit interview.
Call me cynical, but trusting businessmen without checking the facts isn't always wise. Especially in matters of law.
