It is usual in the final weeks of August for lumber sales, thus prices, to drop, as the annual seasonal slow-down arrives.

Both construction activity and sawmilling normally take some down-time when hot temperatures arrive across North America. This year is no different; as the continent-wide Labour Day long weekend loomed many folks were already away from work for that last holiday of summer.
Prices of several lumber and panel commodity groups remained flat.
However, Canadian wood products destined for the US fell significantly, as the attempts in recent weeks to boost prices were rejected by customers. As such operators in Canada had to reduce asking prices down.
Customer counter-offers were just too strong for sawmills to resist. Even so, levels were somewhat higher than in the same week one year, and two years, ago.
In the week ending August 22, 2025 the price of Western Spruce-Pine-Fir 2×4 #2&Btr KD (RL) was US$489 mfbm, which was down by -$44, or -8%, from the previous week when it was $533, said weekly forest products industry price guide newsletter Madisonโs Lumber Reporter.
That weekโs price was down -$19,ย or -4%, from one month ago when it was $508.
As demand continued soft lumber prices remained hard to peg, in many cases because the sharply increased duty rate came into play.
