Harmonized Sales Tax (HST)

On July 1, 2010, Ontario replaced its existing provincial sales tax (PST) system with the harmonized sales tax (HST). Below is a series of communications regarding the transition to HST.

Departments issuing invoices are responsible for knowing the taxation treatment for invoices issued.  If you are unsure, please consult the HST Team before undertaking the activity.

If you have any questions relating to HST, please send an e-mail to the HST Team.  Please allow sufficient lead time when submitting questions to the HST Team as your inquiry may require research and/or consultation with the University's tax advisors and may take some time to obtain a response.
