Sure, I'd be pleased to. It's pretty simple. In most of those, such as subclause 30(3), where it says “Minister may”, change it to “shall” or “must”. It's the drafters' preference, really. It's the same thing. Then for “within a prescribed period of time”, 90 days, for example, might be adequate.
Paragraph 36(a) says the Minister of Fisheries and Oceans “may”, and then paragraph 58(4)(c) says a receiver of wreck “may”:
take, or authorize any other person to take, the measures with respect to the wreck — other than selling, dismantling, destroying or otherwise disposing of it — that the receiver considers appropriate.
Again, I would just say “shall”, within a prescribed period of time.
