Technically, yes, that's the case. They can, however, do some fiddly nonsense with the shipping and billing to get around the regs (making it look like it's coming from the States), but as you noted, it's going to come out of your pocket. Shipping charges on a premium atty (that's obviously expensive enough to qualify for free shipping from any self-respecting vendor) is frickin' ridiculous, especially if they could fix the damned problem with Canadian sales if they gave a crap.
