Canadian taxes are calculated differently from those in the United States. Purium is required to charge Sales Tax on many items sold to Canada. There are three varieties of tax that may be charged, known as GST (Goods and Sales Tax), HST (Harmonized Sales Tax), and PST (Provincial Sales Tax). Depending on the province to which you are shipping items, these charges will be calculated differently. It is the customer's responsibility to be aware of which Purium products are subject to such taxes and how taxes are calculatedĀ in the province of theĀ delivery address.
