Parece que a resposta é não . O parágrafo informativo:
If you are a non-resident visitor to Canada, you cannot claim a rebate of the goods and services tax/harmonized sales tax (GST/HST) that you paid for all purchases made in Canada. The visitor rebate program for GST/HST was replaced on April 1, 2007, with the Foreign Convention and Tour Incentive Program (FCTIP). A non-resident visitor to Canada may be eligible to claim a GST/HST rebate on certain purchases related to conventions or for tour packages under the FCTIP.
