I think in the discussion we had on PV-01, Ms. May's first amendment, we concluded after some discussion that ecological integrity could be an optional criteria for use in designating an interim protected area.
NDP-4 suggests that it be the first priority—if you like, a primary consideration—and there are some significant differences. Obviously, if enough evidence is known, to use it in the optional sense, as was concluded in PV-01, that's one thing, but to have it as the primary criteria, as suggested in NDP-4, would require a baseline to be established, and to go through the rigorous process to establish that before moving to interim protection. The idea of interim protection is to move quickly, using the precautionary principle where not all is known.
