US only gets 31% of their Softwood lumber from Canada and lumber represents a small portion of the cost of the house, the great majority being the land costs. Considering the price of the Canadian dollar the cost to a US home buyer is minimal. What should be concerning is the  stumpage fees in Canada are too low (by 20-25%) and they are generally paid to the province. So you have a province subsidizing big lumber companies cutting down CO2 reducing trees in order to charge you a carbon tax for creating CO2.  We are pissing off the US to make big lumber richer at the taxpayers expense.  Does this make any sense?  BTW When Trudeau added a 43% tax on US drywall back in January no one said a thing.
