Good news for Canucks: Digikey now offers prototype PCB manufacturing with good specs and up to six layers at very reasonable prices with shipping to Canada. They've been offering their DKRed service for a while in the US. It looks like an excellent alternative to OSH Park (not that there's anything wrong with them). The only drawback I see is that they require a minimum of four copies of each board per order.
