I haven't read the whole statute book of course, but I've seen more commonly the type of drafting where it says, “Notwithstanding any other act of Parliament, this provision has effect”. And you in fact see that in the statute you're concerned with, which is the Canada Labour Code. It has a provision in it that specifically says that it takes precedence over any other legislation in the respect that it's concerned with, and that's in part II of the Canada Labour Code, which you were concerned with because it deals with federal undertakings.
