TrueNorth returns exact GST, PST, and HST for every Canadian province, plus validated addresses, in under 40 ms. No more spreadsheets, no more undercharged orders.
TrueNorth is a perfect fit for any personal or business website: one API call handles Canadian tax, address validation, and shipping checks. Every response carries high-quality detail, with per-province breakdowns, per-category rules, and clear totals.
Everything you need to charge the right Canadian tax and ship to a real address.
Exact GST, PST, and HST for any amount in any province, including BC's split tax.
Verify, normalize, and geocode Canadian addresses with postal-code precision.
Current combined and split rates for all 13 provinces and territories, always up to date.
This calls the live TrueNorth backend, the same endpoints you get with an API key.
Tax rates vary by product type, so your store passes a category code with each call, such as category=books. TrueNorth then applies the correct provincial tax rules for that category.
Your store passes the category for what's in the cart.

Platform tax tools only work inside their own checkout and need manual setup per province. TrueNorth delivers correct Canadian taxes anywhere, with a single call.
