I said the largest of them all is in Ontario, split between the north and the south. There is another cluster in Saskatchewan, because of the specialized minerals, such as potash and uranium. In Alberta, between Edmonton and Calgary, there is the oil sands cluster that supports the whole industry. There's another cluster in Vancouver, B.C., with UBC and the other organizations there to support largely open-pit mining. We have open-pit mining elsewhere, but there are more open-pit mines in B.C. than in Ontario. There are deep underground mines in Ontario, specialized minerals in Saskatchewan, oil sands in Alberta, and open-pit mines in B.C.
