I do not have any concrete figures, but I can tell you that members of the Canadian Retail Council often use the figure of 6% in their arguments when they talk about the rebate to people visiting Canada. When one of our members sells a product that is sufficiently expensive, for example, a handbag worth $3,000 or $4,000, the 6% rebate becomes a valid argument. Once the person has left the store, there is no way to know whether he or she will claim the rebate back home, but the sale has taken place. In any event, the money stayed in Canada.
