I suppose I can't just give a response similar to the one for Mr. Amos, that I'll get back to you in writing.
Part of what I want to emphasize goes back to my concluding remarks on the kinds of things that I think would certainly help in terms of completing a systems plan: political leadership and commitment. I think we have enjoyed that going back to 1989 and the green plan. There's also public and stakeholder support.
It's not just about science. I would say to the committee that you can have the best science, and you can have different levels of science input. We have a good idea of the areas we want to protect. But it really does take the time to build the necessary trust and commitment you need from other governments that are prepared to transfer the land, the surface, and the subsurface to us, and securing the trust of indigenous communities and people. We have found in some places that takes time. Sometimes they're ahead of us, sometimes we're ahead of them. Having the ongoing support and funding to be able to invest in delivering those relationships is critical.
I will not say to the committee that we can absolutely do that in four years, because I think our track record is that in some communities where they're changing leadership, changing conditions, it does take time. I think all of us in each department are facing that challenge of meeting the targets, but building it in such a way that we are respectful of the nation-to-nation relationship that we need to address.
I think consistent leadership, consistent commitment, consistent funding, consistent support, at times making the necessary decisions around particular boundaries—that's the way to go.
