There is no question that tariffs will increase the cost of lumber and thus house framing costs. It will not, however, have a great deal of impact on Canada's major lumber producers for two reasons. The first is the fact that these producers now supply over 30% of American demand from mills they have purchased in the US. They will benefit from any increase in price. The second reason is that mortality from the pine beetle infestation in BC and Alberta has reduced and will continue to reduce log supplies. It will be neccessary for producers there to close mills no matter what occurs in the way of tariffs and prices. Most likely, what is produced in those provinces will be used to supply growing offshore markets. Both US and American producers will, however, suffer if prices exceed $500.00US per thousand board feet given that such a price would make substitute studs made from steel competitive. American log owners and their lobbyists should be very careful of what they wish for.
