I've checked all the Canadian stores of the companies mentioned and non of them sell your product. It is way simpler and cheaper to order from a company in Canada who has already dealt with all the cross border issues, Taxes and duties. Not to mention the ability to walk into a store and buy it directly and save the shipping costs.
I'd suggest you guys try and find someone in Canada to carry this product.
I think you are out of luck, I can't find anyone anywhere in Canada that sells this product. You will need to order it from Hava directly or from another online retailer in the States, and go through the hassle of getting it across the border.
