I don't think importing Canadian studs would make much of a difference, since they seem to be raising their prices too.

"Softwood lumber prices just kept climbing last week as Canadian housing starts and home prices for July broke records. U.S. housing starts this week were no different; new home building in the U.S. increased +23 per cent in July — the biggest gain since October 2016 — to a seasonally adjusted annual rate of 1.496 million units, the U.S. Commerce Department said Tuesday. Single-family construction rose by more than +8 per cent and single-family permits increased +17 per cent to a 983,000 rate, the strongest since February. The number of residential projects authorized but not yet started also advanced, to 101,000 units in July, the biggest backlog since the end of 2018."
A custom builder buddy said that the lumber package for the exact same custom home, 2,000 s.f., 3 car att., has increased $15,000 since January. The customer decided to wait 6 months to start and when he re-ran the bids, that's what the lumber yard quoted, went from $55K to $70K, same house plans.
