That's an excellent question. It is extremely site-specific and region-specific. Domtar is a corporation that operates in the interior of British Columbia. As I said, we're in Ontario and Quebec, but we also operate down in various regions of the United States, including the Appalachian Mountains in the southeast. The nature of the supply chain will be a function of regional conditions, and that's true for the whole industry. In our Kamloops, British Columbia, mill, we're 100% residual. We are full, and we do not own any of those sources of the residual chips. The chips are coming to us through sawmills. Kamloops used to be a warehouse at the time they were integrated with the sawmill, but that has since been “disintegrated”, if you will.
In that regard, a healthy lumber industry is absolutely critical to our supply chain and our input costs. If anything happens to reduce the activity on the sawmill side, our costs go up. We have some provisions for chip mills to chip whole round logs—usually juvenile thinnings—to sort of supplement sawmill chips, but those would come at a greater cost.
That's the first part of the answer. Then, if you look at other facilities like our Windsor, Quebec, mill, our Windsor, Quebec, mill is in a hardwood forest and there's very, very little milling of that for structural lumber. We have extremely large, internal whole-log chipping operations. To answer your question, we have anywhere from 0% to 100% residual chips coming into our facilities. Fifty-fifty is not unusual. If sawmill residual chips are available, generally, those are the preferred source of fibre because they will, generally, be at the lowest cost.
Does that answer your question?
