The rate that applies is the one in force when the tax became payable, which is usually the invoice or payment date, so older receipts may show a previous rate.

Registering and collecting tax in Ontario

HST is administered by the Canada Revenue Agency (CRA). Businesses register, charge and remit it through a single GST/HST account. Most businesses must register for GST/HST once their worldwide taxable sales pass $30,000 over four consecutive calendar quarters. For GST/HST, sellers based elsewhere in Canada charge the rate of the province the goods are delivered to, so a sale shipped to Ontario carries Ontario's GST/HST rate.
