Wood preservation

This Canadian industry comprises establishments primarily engaged in treating lumber, plywood, poles and similar wood products, produced in other establishments, with preservatives to prevent decay and to protect against fire and insects. Pressure treating is the most common method used. — Statistics Canada, NAICS 2022A

Size and shape

How many businesses there are and how small they are. Fragmentation is the first thing an entrant — or anyone selling software into this industry — needs to know, and it is one of the few things that is actually measured.

Measured, not forecast: the share of US establishments opening in one year that were still active later. It counts good operators and bad ones together, which is exactly why it is the honest answer to “what are the odds”. It is for the whole sector rather than this market, and the ten-year figure comes from an older cohort because no younger one has reached ten years.

How businesses here compete

The structural profile of subsector 321, which every industry beneath it inherits. This is analyst judgment from how the subsector is organised — not research into this industry, and not a measurement.

regional competitionhigh capitalUNVERIFIEDinherited from 321 Wood product manufacturing

Sawmilling is a commodity tied to fibre supply. Value-added work — millwork, trusses, engineered components — is regional, freight-protected and more reachable.

Who sets the price: Lumber and panel commodity markets; builders for value-added products.
The software it runs on: Mill optimisation, inventory and log accounting.

binding constraint: capital intensity

Two businesses share this code and they have opposite years. Wood preservation is the attractive one: Stella-Jones sold C$3,492M of treated poles, ties and lumber in 2025 at an 18.9% EBITDA margin, with utility products alone at C$1,822M and rising [A]. But its customers are electric utilities and Class I railways buying on multi-year supply programmes, its moat is a continental network of treating plants plus pole-quality fibre under contract, and it spent C$259M on acquisitions in 2025 absorbing what adjoins it [A]. A new treating plant is a permitted, capital-heavy site with two or three possible customers per region, each already supplied. Sawmilling is the reachable-looking one and the numbers are worse. The Value-Added Wood Manufacturing record cuts small sawmilling on fibre supply; this screen adds what happens at the border. Interfor lost C$344.4M on C$2,805.9M of sales in 2025, booked a C$69.1M impairment on its Eastern Canadian mills, and has US$663.5M of cumulative duties on deposit; the combined countervailing and anti-dumping rate is 35.16%, with a further 10% Section 232 tariff on top [A]. That is cash paid before the customer pays, on a commodity averaging C$599 per thousand board feet in the fourth quarter. The size bands say this is a plant industry — 199 of 726 establishments employ fifty or more [A] — and a mill is sunk capital whose working capital is then taxed at the border. The small custom and portable mills that make up the bottom of the count sell locally and avoid the duty, and are the subject of the other record.

binding constraint: growth quality

The constraint is fibre, and it is getting worse rather than better. Canfor wound down its Polar sawmill north of Prince George explicitly for 'a shortage of economically available fibre', removing about 140 million board feet over six months, and West Fraser lost $937M on sales that fell to $5.462B from $6.174B under softwood duties, oversupply and soft demand. A small entrant buys fibre in the same market as those two and sells into the same prices, without their tenure. The value-added niches — mass timber components, remanufacturing — are real and they sit downstream of a supply problem no operator can solve alone.
