That's fine. As regards the 23-day period, that corresponds to subsection 19(5) of the act, which the bill would amend under subclause 8(2).
It states:
(2) Notice of the time and place fixed by the commission for any sittings to be held by it for the hearing of representations from interested parties shall be given by advertisement published in the Canada Gazette and in at least one newspaper of general circulation in the province at least thirty days before the day on which the sittings commence.
Here a period of 30 days is proposed, but I think the current period of 60 days is more appropriate.
