I think what we're striving for at the moment is what we've already promised to do, which is to meet the Convention on Biological Diversity guidelines of 10% marine and 17% terrestrial lands.

As my colleague Jeanette Whitton said, a lot of the pressure is coming in the southern portions of Canada, and this is where, relatively speaking, we lack protected areas.
