Mass Timber Construction Success Checklist
Mass timber construction offers speed, sustainability, and design flexibility – but it also requires a higher level of coordination than traditional structural systems. Its prefabricated components and tight tolerances call for early planning, clear communication, and a shared understanding across the project team. Ensuring that all partners – including those less familiar with timber construction – are aligned on these unique requirements helps avoid costly delays and, more importantly, positions the team to fully capitalize on the benefits mass timber has to offer.
Exploring the Role of Mass Timber – Industrial Buildings and Warehouse Construction
The emerging use of mass timber in industrial buildings presents promising opportunities that are shaping the future of construction in this sector. As a sustainable and economically competitive alternative, mass timber is redefining industrial construction, a field traditionally dominated by prefabricated steel. An analysis of two cutting-edge projects in Sudbury, Ontario, highlights key advantages, including cost competitiveness, reduced embodied carbon, and aesthetic appeal. The insights from these two projects present stakeholders with helpful considerations and valuable strategies for integrating mass timber into future developments.

Wood Decay and Repair
LEAKY BUILDINGS AND DECAYING WOOD – WHAT’S HAPPENING? The news across North America seems to frequently contain stories about serious moisture failures in wood-frame buildings. Whether it’s Vancouver’s “leaky condo crisis” or the “EIFS disaster” in North Carolina, homeowners are struggling with wood decay wherever the other components of the building’s walls and roof aren’t properly protecting the wood structure from excessive moisture. Interestingly, leaks are also getting attention in steel and concrete high-rises, causing rust in steel studs and fasteners and degradation of gypsum wallboard. Why are we suddenly finding so many failures in buildings, including in our tried-and-true wood construction? This is a frustrating problem for everyone in the building industry, because there are no easy answers. It’s convenient to blame unskilled or unethical practitioners in the building industry. Other occasional targets for blame include municipalities for developing zoning ordinances that conflict with performance issues; energy efficiency codes for making our building envelopes tighter; new and complicated materials in our building envelopes; the building occupants for not practising proper maintenance; or the wood, which some seem to feel has declined in quality. The bottom line: many people have opinions, but so far there is little firm technical data to answer these questions. Please see our Links page for some of the research institutions working in this area. Buildings have probably always leaked, although it is only recently that moisture seems to be a problem. Some believe that the difference is that today’s buildings are less tolerant of those leaks; that perhaps the older buildings were able to dry out. Another theory is that today’s leaky buildings leak more than in the past, due to design errors, sloppy construction, lack of overhangs, etc. Thankfully, many people working in the building industry have turned their attention towards better design and construction practice for moisture control. A number of “best practice guides” are listed in our Links section. HOW CAN I TELL IF WOOD IS DECAYED? If wood is badly decayed, this will be quite obvious. The wood will be soft and perhaps even be breakable by hand. Decayed wood breaks with a carrot-like snap versus the splintering of sound wood. Use the pick test to be sure. MY WOOD IS STAINED – IS IT DECAY? Probably not, if this is new lumber. There are many harmless sources of wood stains, including dirt, iron filings, or staining fungi that merely colour the wood without damaging it. Please see the fact sheet “Discolourations on wood products: Causes and Implications” for a thorough explanation including photos. If the discoloured wood is found in a leaky building under repair and may have been wet, perform the pick test to see if it is rotted – see our page on Assessing decay. I HAVE DECAYED WOOD – WHAT SHOULD I DO? Remove all decayed wood and additionally remove another two feet of sound wood all around the decayed section. Any sound wood that is left in place when decayed wood around it has been removed should be field treated with a penetrating preservative. Also field treat any wood that may continue to get wet after repairs. We recommend preservatives containing a diffusible low-toxicity fungicide such as sodium borate, and low-toxicity formulating agents which assist in penetrating dry wood, such as propylene glycol. By the time the cladding has been removed, the structure has been inspected and the decayed wood has been removed, the wood left in place will likely have dried too much for effective use of formulations without a penetration aid. Under conditions of high relative humidity, the propylene glycol may cause a short term increase in the moisture content at the wood surface. For more information, please see our page on Assessing decay. IS KILN-DRIED LUMBER MORE RESISTANT TO DECAY THAN GREEN OR AIR-DRIED LUMBER? One advantage of kiln-dried lumber is that any live fungi present in the green lumber will have been killed by the heat of the kiln; in other words, KD lumber is sterile after leaving the kiln. However, if it gets sufficiently wet afterwards, then it is at the same risk of decay as any other wood. ARE COMPOSITE WOOD PRODUCTS MORE RESISTANT TO DECAY THAN SOLID LUMBER? No. Composite products (glulam, OSB, laminated veneer lumber, etc.) have the same resistance to decay as the wood from which they were made. The adhesives used in composites do not affect decay resistance. DO WE HAVE TERMITES IN CANADA? Yes, in a few limited areas across the country and to a greater extent around Toronto, termite species causing damage to buildings are present. Although termites are a significant problem in parts of southern Ontario, overall they are only a mild concern in this country. They prefer warmer conditions and are a far greater problem in parts of the United States. In Canada we do not have the voracious Formosan subterranean termite causing so much damage in the southeastern US. WHAT IS DRY ROT? Contrary to popular usage, dry rot does not mean rot that can happen in dry wood, or wood that has rotted and dried out. Dry rot is a specific kind of fungus, although the term is very commonly misused to describe all wood rot. This is unfortunate, because it disassociates rot from moisture. Wood rot always requires moisture, and the key to wood durability is the control of moisture. Wood that rotted long ago and is now dry was moist at the time of the rot. The true dry rot fungus has the ability to tap into a water source and conduct water to what would otherwise be dry wood. However, it has to wet the wood before it can attack the wood. The true dry rot fungus is more likely to be found in buildings that contain brick or stone than in all-wood buildings. HOW FAST DOES WOOD DECAY? It’s impossible to say; there are so many variables that influence the process. In a laboratory, under ideal conditions for decay fungi, wood can rot quite quickly.

Design for Deconstruction in Light Wood Frame
The Guidebook of Design for deconstruction in Light Wood Frame presents a methodology for altering typical light wood frame assemblies so that they can be easily disassembled and the materials of the building can be reused. The province of BC and, more broadly, Canada, has relatively little infrastructure for recycling wood waste. In Vancouver alone, the construction, renovation, and demolition (CRD) sector produces about 1.7 million tonnes of waste per year.1 Of this, an estimated 30-60% is wood waste which is largely discarded in landfills. What little wood that is recycled is generally incinerated for waste-to-energy conversion or shredded for biomass. Deconstructing wood buildings and reusing the salvaged wood for new construction would extend the lifespan of the wood, add value and longevity to a valuable material, reduce GHG emissions and reduce the amount of new resources required for new construction projects. Despite the benefit of re-using wood, there are some barriers to deconstructing typical light wood frame buildings, including the use of irreversible fasteners, adhesives, spray foams, and liquid applied sealants. The presence of toxic materials such as asbestos and lead are also of concern when deconstructing a building. While use of toxic materials is now prohibited in new constructions the use of nails (particularly when applied with nail guns) and adhesives makes deconstruction very difficult if not impossible in some cases.2 This guidebook proposes a design for deconstruction system that addresses these remaining issues with simple modifications of typical light wood frame construction practices, allowing for both simple construction, solid performance, and easy deconstruction.
Wood Design & Building Magazine, vol 24, issue 96
Buildings that stand the test of time aren’t just durable—they are cherished. When we invest in quality materials and good design, we can create buildings that people connect with. As you’ll discover in this issue, many heavy timber warehouses and factories constructed in the early 1900s remain a vital part of our cities today—not because they still serve their original purpose, but because people valued them enough to adapt, restore, and reuse them, giving them a new purpose. Fast forward a hundred years and resilient structures include many new forms. Modular construction, for example, has seen significant growth in recent years as this form of construction has transformed from a building method once considered inferior, into a method relied upon to deliver high-performance durable buildings. Alongside our features on historic timber buildings and modular construction, this issue also highlights notable projects and emerging trends shaping today’s built environment. From innovative mass timber structures to forward-thinking design solutions, we explore how thoughtful craftsmanship and smart engineering continue to define the spaces we build—and the ones we keep.

Cunard Street: Live / Work / Grow Building
The new home for FBM is constructed on a 50 ft by 100 ft brown field site in the north end of Halifax; close to the city’s Commons. A one-storey transmission shop was previously located on the site, making the soil and bedrock remediation necessary to allow for the current development. Site plan The Commons, in the centre of the city, forms a green swath of space for recreation, sports fields, and well-being. Surrounding the site is a mix of occupancies, including social housing for seniors, small scale businesses, day cares, bars and restaurants, military uses at the Halifax Armory for the Princess Louise Fusiliers and Cadet units, Urban agriculture, and several architecture firms that have recently chosen this area for their new offices. The design of the new Cunard St Live/ Work/ Grow building embodies the values of FBM Architecture – a place for ‘people driven design’. This is expressed through the firm’s interest in contributing to the community, through the materials, and the work culture that the building supports.
Canadian Wood Council Applauds Strategic Federal Investments in B.C.’s Forest Industry
OTTAWA, March 25, 2025 – The Canadian Wood Council welcomes the Government of Canada’s announcement of over $20 million in funding for 67 projects that support the growth and resilience of British Columbia’s forest sector. While the announcement includes several strategic large-scale investments in advanced wood manufacturing, a significant strength of this initiative lies in the breadth of smaller-scale, high-impact projects that are collectively transforming communities across the province. From feasibility studies for Indigenous-led forest product businesses to the development of next-generation building technologies, these projects are advancing wood innovation, supporting workforce development, and expanding the role of wood in low-carbon construction. Administered through Natural Resources Canada, this Green Construction through Wood (GCWood) funding supports a wide range of initiatives—from fire-testing mass timber connections and refining modelling guides for timber structures, to developing bioenergy solutions and value-added wood processing in Indigenous communities. This announcement underscores the importance of decentralized innovation, where targeted investments in communities and research institutions alike contribute to a stronger, more sustainable forest sector. The Canadian Wood Council applauds this commitment and looks forward to continuing its work with design professionals, governments, and industry partners to support the expanded use of wood in the province through its market-leading WoodWorks program.
