Spruce, pine, fir (SPF) dimension lumber is used in a variety of applications, including residential and commercial construction, fencing and decking.

Millar Western lumber is produced in dimensions ranging from 1x3" to 2x10", and in lengths from 6' to 16'.   We also manufacture machine stress rated (MSR) lumber for engineered roofing and load-bearing applications, 5/4" lumber and timbers for decking material, a special grade for export to Asia, and other specialty wood products.

Each piece of lumber we produce is marked with a grade stamp indicating its quality and intended use. We grade our lumber according to demanding standards set by the Canadian Lumber Standards Accreditation Board (CLS) the North American Lumber Grading Association (NLGA), and the Japanese Agricultural Standard (JAS). The Alberta Forest Products Association regularly inspects our grading practices to ensure they comply with the requirements of these grading agencies.

All Millar Western lumber products are made with timber sourced from sustainably managed forests.  Both the Whitecourt and Boyle mills are certified to the SFI sustainable forest management standard and under FORESTCARE, the Alberta forest industry's demanding code of practice governing care of the forest, environment and communities.  Whitecourt operations are also certified to the PEFC and FSC® chain-of-custody standards and Boyle, to the FSC chain-of-custody standard.

With the start up of the new Fox Creek mill in November 2011, Millar Western's annual lumber production capacity expanded to over 530 million board feet.  Most of its lumber products are shipped to customers in Canada and the U.S., with a small but growing proportion destined for Asian markets.

A part of the province's lumber industry since the 1920s, Millar Western is today the largest Alberta-based producer of SPF dimension lumber.
