I'd buy stuff that said "made in Canada".
Someone that I know works at the Canadian/U.S. Border (Customs agent). Apparently a LOT of lumber crosses the border there.
/me sings the Monty Python 'Lumberjack' song since I'm thinking of it now
actually there's this one Canadian company that makes circuit boards, and they're one of the fastest I've seen at doing prototypes for designs. FedEx results back in 5 working days from when I submit the designs. I've submitted them electronically on a Sunday (evening) and received boards on Thursday. It's pretty cool.
