If you sell goods or services to customers outside of Canada, you are not required to collect GST/HST or PST, provided they take delivery of the goods or services outside of Canada. The service must be wholly used outside of Canada. If non-resident customers, such as tourists, make purchases within your province or territory, they are required to pay the GST/HST and PST. In some cases, they may be eligible to receive a GST/HST rebate.
