Impact on Your Procurement Strategy
Bernie McGlynn Lumber’s CA$5.3 million expansion in Mildmay, Ontario, will raise mill output by nearly 50% by late 2026. This project includes a 30,000-square-foot facility and a thermal kiln focused on the outdoor decking market. For distributors in Eastern Canada, the investment increases local supply and lessens the need for imports. The Ontario government is providing $1.6 million through the Forestry Sector Investment and Innovation Program to support the project. While framing lumber demand is currently flat, the new kiln capacity is intended to prevent seasonal shortages in specialty treated wood by the Q3 2026 building season. Market data shows framing lumber prices recently rose 3.3%, but the trend is slowing after three weeks. Procurement managers should avoid building large inventories and maintain 14-day replacement cycles. With a 1.1% price change expected in the next week, adding regional sources like McGlynn helps manage supply chain risk.
