Hey Folley, you're in Washington, I'm in Washington. Feel like doing some volunteer work with us and helping us nail down shipping to Canada? If so, send me a PM. It's not volume of reagent, I think it's simply declaring the items and values of the items correctly (ie navigating import restrictions and taxes). We've had some success doing custom orders lately, but aren't sure if it scales well enough to do it for retail orders.
Also, you can indeed get kits in Canada, just contact TRIP! in Toronto. We were able to get a bunch up to them in person and they're handling Canadian distrubution. tripproject.ca is the website.
