I'll say two things, and then I'll turn to my colleague Eugene.
When we take a look at the Australian model, as you indicated, we see a lot of comparables between Australia and Canada in terms of geography and some of the challenges and opportunities that arise. What we're finding is that it's a fairly complex issue that often brings a lot of different factors into consideration. There are things like universality, which is making sure that everybody in the country is treated the same in terms of service delivery, and that has implications in terms of cost. Also, some places simply might be a little easier to deliver to, which usually means that it's less costly.
What I would say is that as the committee looks at this subject, it will see that there's a fair amount of complexity in some of these issues that I think we're learning about.
Go ahead, Eugene.
