OTTAWA, March 24, 2025 – The Canadian Wood Council (CWC) applauds the joint investment of over $8.5 million by Natural Resources Canada and Quebec’s Ministry of Natural Resources and Forests in four innovative wood construction-related projects across Quebec. These strategic initiatives will help strengthen the manufacturing sector and accelerate the adoption of low-carbon, Canadian-made wood products and technologies in residential construction and other critical community infrastructure.

By supporting advanced wood construction methods—including modular mass timber housing, artificial intelligence to modernize engineered wood manufacturing, and the design of tall wood residential buildings—this investment reinforces the essential role of wood in delivering high-performance, low-carbon construction solutions. From a 20-unit modular development and a 21-storey design study to the cultural leadership of the Cree First Nation of Waswanipi in forest-to-form construction, these projects demonstrate how innovative wood technologies can meet urgent housing needs in a sustainable way, through scalable and repeatable, locally driven approaches.

The Canadian Wood Council commends both levels of government for recognizing the critical role of Canada’s forest sector in delivering smart, climate-friendly building systems. These investments demonstrate how advanced wood technologies can contribute to addressing urgent housing needs while helping to lower the carbon footprint of the built environment.

Design and construction professionals in Quebec can access free technical support related to wood design and construction through the market-leading resource program, Cecobois. The CWC is pleased to provide support further expand the use of wood in residential, commercial, and institutional buildings throughout the rest of Canada through its WoodWorks program.

The Canadian Wood Council is proud to share the National Lumber Grades Authority (NLGA) latest updates to the design values for Hem-Fir (N) dimension lumber, effective April 1, 2025. These changes result from a routine reassessment of strength and stiffness properties, ensuring Hem-Fir (N) continues to meet structural performance expectations.

Key Points:

  • Minimal Practical Impact: The updated design values should not result in significant changes to the practical use of Hem-Fir (N) in most applications, maintaining continuity for builders, designers, and engineers.
  • Consistent Performance: Hem-Fir (N) remains a trusted and dependable choice for residential and commercial construction, with values that closely align with previous standards.
  • No Impact on Existing Construction: Structures built under previous building codes remain compliant.
  • The updates are reflected in the NLGA Standard Grading Rules for Canadian Lumber, CSA O86 – Engineering Design in Wood, and the National Design Specification® (NDS®) Supplement for Wood Construction.

For additional details, including specific design value changes, affected lumber grades, and implementation considerations, please refer to the Frequently Asked Questions (FAQ) document for Canada or the USA.

Some engineered wood panel products, such as plywood and laminated veneer lumber (LVL) are able to be treated after manufacture with preservative solutions, whereas thin strand based products (OSB, OSL) and small particulate and fibre-based panels (particleboard, MDF) are not. The preservatives must be added to the wood elements before they are bonded together, either as a spray on, mist or powder.

Products such as OSB are manufactured from small, thin strands of wood. Powdered preservatives can be mixed in with the strands and resins during the blending process just prior to mat forming and pressing. Zinc borate is commonly used in this application. By adding preservatives to the manufacturing process it’s possible to obtain uniform treatment throughout the thickness of the product.

In North America, plywood is normally protected against decay and termites by pressure treatment processes. However, in other parts of the world insecticides are often formulated with adhesives to protect plywood against termites.
