An Efficient and Flexible Producer of High Quality Lumber. With a capacity of approximately 500 million board feet of lumber annually, Dunkley is one of the largest sawmills in North America. We process predominantly SPF (White Spruce, Lodgepole Pine, and Alpine Fir), however Douglas Fir is also a component of the log mix. A long-standing commitment to modernization and efficiency has allowed us to maintain a strong position in British Columbia’s forest industry.
