It's fairly stable. The way it works is that we have some stations at which we take measurements specifically for our own use, so they're designated federal stations. We do some at the request of the provinces or the territories. Then there are some that we're both interested in, so we cost-share.
We review the list each year and the agreement regarding what the specific stations are. On the federal side, it's fairly stable. The provinces and territories will adjust depending on what specific activity there is. For example, if there's a new mine, they might ask us to add a couple of stations, but that's their decision.
