OK, I don't know anyone who stocks them. Urbane has Otlieb in stock, And they might have the odd tubus. They don't stock the range. There aren't any surly racks either. Part of the reason why I am making my own.

If you do bring them in, make sure they are sent USPS (Post Office). That way you pay only the 5 dollar clearing fee, and the taxes. Which means on small orders you sometimes don't even get charged taxes, which is cheaper on every basis than buying Canadian, except postage.
