Ontario Building Code
Ruling No. 09-08-206 (12904-R) authorizing the use of this product in Ontario, subject to the terms and conditions contained in the Ruling, was made by the Minister of Municipal Affairs and Housing on 2009-04-16 (revised 2015-09-28) pursuant to s.29 of the Building Code Act, 1992 (see Ruling for terms and conditions). This Ruling is subject to periodic revisions and updates.
The above opinion is based on the evaluation by the CCMC of technical evidence provided by the evaluation holder, and is bound by the stated conditions and limitations. For the benefit of the user, a summary of the technical information that forms the basis of this evaluation has been included.
Product information
Product name
West Fraser™ LVLProduct description
The product is a laminated veneer lumber (LVL) (see Figure 1) that is manufactured by laminating veneers of Lodgepole pine, Douglas fir, aspen and white spruce singularly or in combination at the Rocky Mountain House plant. The grain of the veneer is oriented parallel to the length of the member. The 3-mm-thick veneers are bonded with an exterior-type phenolic resin (phenol formaldehyde) complying with CSA O112.10-08, “Evaluation of Adhesives for Structural Wood Products (Limited Moisture Exposure)” (see CCMC 13192-L). The veneer joints are scarfed or lapped and staggered with a minimum distance between joints of not less than 100 mm. The lengths and widths are cut in square edges.
Five grades of the product (1700Fb-1.3E, 2750Fb-1.7E, 3000Fb-1.8E, 3000Fb-1.9E, and 3100Fb-2.0E) are available in 25.4-mm to 89-mm thicknesses, 89-mm to 1 219-mm depths, and a maximum length of 24.38 m.
Quality control and testing is conducted by APA – The Engineered Wood Association (APA-EWS) as an independent third-party monitoring and inspection agency accredited by the Standards Council of Canada.

Conditions and limitations
The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.
- The product, as with all SCL, is intended for dry-service applications only.Footnote (1)
- The product is intended for use in construction as an alternative material to lumber. Proprietary design values presented for the product are to be used by professional engineers for design in accordance with CSA O86-14, “Engineering Design in Wood,” for structural applications such as beams, headers, joists, rafters, and columns as intended by the product manufacturer. The specific application must be qualified through specific testing and validated by the manufacturer. Applications such as I-joist flanges, studs and metal-plated truss chords are beyond the scope of this evaluation.
- The pre-engineered tables in the literature outlined below have been provided to the CCMC by the manufacturer to demonstrate compliance with Part 9 buildings for acceptance by the local authority having jurisdiction (AHJ):
- Manufacturer’s pre-engineered tablesFootnote (2)
- When the product is used as floor beams in simple spans supporting uniform loads only, the installation must be in accordance with the content of the manufacturer’s publication entitled:
- “West Fraser™ LVL User’s Guide,” version Canada v0415v3;
- The product must be installed in accordance with the manufacturer’s installation guidelines noted in this document for those applications falling within the scope of the document. Applications outside the scope of these installation guidelines require engineering on a case-by-case basis.
- When the product is used as floor beams in simple spans supporting uniform loads only, the installation must be in accordance with the content of the manufacturer’s publication entitled:
- Manufacturer’s installation details
- Nails and bolts in the attachment of the product must be used and installed in accordance with the manufacturer’s size and spacing specifications.
- The ends of all beams must be restrained to prevent rollover.
- The compression edges of all beams must be continuously laterally supported.
- Engineering required
- For structural applications beyond the scope/limitations of the above-referenced publication, or when required by the AHJ, the drawings or related documents must bear the authorized seal of a professional engineer skilled in wood design and licensed to practice under the appropriate provincial or territorial legislation.
- The product must be designed in accordance with the requirements of CSA O86 and Part 4 of Division B of the NBC 2015. The specified strengths and fastener limits for the product must not exceed the values set forth in the Product specified strengths for dry-service conditions and Product fastener capacities tables in this evaluation.
- The engineer must design in accordance with CSA O86, and may use as a guide, the “Engineering Guide for Wood Frame Construction,” published by the Canadian Wood Council
