I may be entering too fully into the spirit of negotiation here, but I want to emphasize to members that provinces have told us that the more the act imposes rules from the outset, the more it appears that big brother is telling them what to do, and that's a deterrent to coming to the table.
An alternative could be to amend subsection 10(8) in Bill C-30 to require that an agreement specify a termination date. Then you wouldn't have a five-year, which might be inappropriate in some cases, but you would have the assurance of some kind of termination date.
