How this calculator works
Canada has one federal goods and services tax (GST) of 5%. Some provinces harmonize it with their provincial sales tax into a single HST: 13% in Ontario, 12% in British Columbia (since April 2025), and 15% in New Brunswick, Newfoundland, Nova Scotia and Prince Edward Island. Alberta, Saskatchewan, Manitoba, Quebec and the territories charge the 5% GST alone, with separate PST/QST on top in SK (6%), MB (7%) and QC (9.975%). To add tax, multiply by 1.13 in Ontario; to remove it, divide by 1.13. Worked example: $1,000 before tax in Ontario becomes $1,130 with 13% HST — $130 of tax. Many basics are zero-rated (most groceries, prescriptions, medical devices) and some items are GST/HST-free entirely.
Frequently asked questions
Which provinces use HST?
Ontario (13%), British Columbia (12% since April 1, 2025), and New Brunswick, Newfoundland & Labrador, Nova Scotia and Prince Edward Island (15%). The other provinces and territories use the 5% GST alone, sometimes with a separate provincial sales tax.
How do I remove HST from a price?
Divide the price by 1.13 in Ontario (or 1.15 in Atlantic Canada). For example, a $1,130 price in Ontario contains $130 of HST: 1,130 ÷ 1.13 = 1,000. Dividing by 0.13 instead gives the wrong answer — a common mistake.
What items are exempt from GST/HST?
Most basic groceries, prescription drugs, medical devices, most childcare, and many healthcare services are zero-rated or exempt. Notably, GST/HST was also permanently removed from new rental housing construction to encourage development.
Do businesses pay GST/HST?
Registered businesses collect GST/HST on sales but claim input tax credits to recover the tax they paid, so the tax ultimately falls on consumers. Small businesses under the $30,000 revenue threshold can choose to stay unregistered and not charge tax.
