Yes, it's an interesting point. I think you go in with your U.S. supply chain partner arm-in-arm, so that you don't come in as completely foreign. Also, you'd have to identify the relative cost benefit of partnering with a Canadian partner.
You know, Canada is closer to a lot of manufacturing places in the United States than places in the United States are, so when you make the case and you bring in your American partner, you have a pretty good chance at getting the waivers you need from the White House.
