Tourists visiting Canada are generally not eligible for a refund of the GST/HST paid on purchases made in Canada. The GST/HST visitor rebate program was discontinued, and non-resident visitors cannot claim a rebate for most goods and services bought during their trip.
Some exceptions apply for foreign conventions or tour packages, but these are limited and specific. For more details, see the Foreign Convention and Tour Incentive Program.
