The single biggest source of those revenues is the services we provide to the Canada Border Services Agency. We share a certain IT infrastructure, which we own and operate, and we charge them for that amount.
So they pay us. Effectively, we are just recovering our own expenses, and then our legislation gives us the right to re-utilize that funding.
That's one example; as I say, it's the biggest example. But there are others. They extend also to such things as the fees we would charge for giving advance tax rulings. That's a much smaller amount in total magnitude, but the principle is the same.
