That's a good question.
I think lots of places started with our model, and some have slowly evolved. We've done a lot of work in looking at this. Sometimes they've evolved into forms of privatization, moving forward to fully privatize. When we've looked at this in the last few years we've noticed that a fully privatized model will actually be more expensive. Because we already are a high-cost place to travel in Canada, it would be a challenging way to go.
We need to look at ways within our own model for how we can make it better, more efficient, and how government can be a partner in doing that.
