HST Ontario rate: what your business needs to know

Last updated: October 18, 2026

The HST rate in Ontario is 13%, and it hasn’t changed since July 1, 2010. You can confirm this figure any time using the Canada, which the Canada Revenue Agency (CRA) updates directly.

Here’s the quick breakdown:

• Total HST in Ontario: 13%
• Federal component (GST): the fixed federal rate
• Provincial component: the Ontario-specific portion
• In effect since: July 1, 2010

That stability matters if you’re running a business in Nova Scotia that ships to or invoices Ontario clients. You need to know which rate applies to which transaction, and that’s not always as obvious as it sounds.

What is Ontario’s HST rate right now?

As of 2026, Ontario’s HST rate is confirmed at 13% on the CRA’s official rates page, the definitive source for verifying any provincial rate before you invoice a client or file a return. Ontario’s own government page also confirms the 13% figure and notes that HST has been in place since July 2010, with certain point-of-sale rebates reducing the provincial portion on specific items like children’s clothing and printed books.

If you’re reading this from Nova Scotia, you’ll want to know that your home province’s rate recently moved. Nova Scotia’s HST dropped from 15% to 14% effective April 1, 2025, bringing it down to a 5% federal and 9% provincial split.

Quick facts worth bookmarking:

• Ontario HST: 13% (5% GST + 8% provincial), unchanged since 2010
• Nova Scotia HST: 14% (5% GST + 9% provincial), effective April 1, 2025
• Where to verify: CRA’s GST/HST rates page, updated whenever a province changes its rate

HST rates across participating provinces

Not every province charges HST. Some blend GST with a provincial sales tax (PST) that’s collected separately, and a few charge GST alone. For businesses operating across provincial lines, a quick comparison helps you spot which rate applies where.

These figures reflect the rates confirmed on CRA’s calculator and cross-checked against the Retail Council of Canada’s sales tax summary. Provinces like Alberta, British Columbia, Saskatchewan, and Manitoba don’t participate in HST at all. They either charge GST plus a separate provincial sales tax or, in Alberta’s case, GST alone with no provincial sales tax whatsoever.

If you’re doing business in more than one province, don’t rely on memory or an old invoice template. Rates change, as Nova Scotia just proved, and the CRA’s rates page stays current the moment a change takes effect.

How do you know which HST rate to charge?

This is where a lot of Nova Scotia business owners trip up when they start selling to Ontario clients. The rate you charge isn’t based on where your business is located. It’s based on the place of supply, which generally means where the customer receives the good or service.

Here’s how that plays out in practice:

1. Shipping physical goods: If you’re a Halifax retailer shipping a product to a customer in Toronto, you charge Ontario’s 13% HST, not Nova Scotia’s 14%. The delivery address controls the rate.
2. Delivering a service: If you’re a consultant based in Nova Scotia working with a client whose business address is in Ontario, the recipient’s address usually determines the rate, meaning you’d charge 13%.
3. In-province transactions: If both you and your customer are in Nova Scotia, you charge the local 14% rate.
4. Mixed-location contracts: For more complex service arrangements, CRA’s charge-and-collect guidance walks through specific examples for goods, services, and real property.

Pro Tip: When a province changes its rate mid-contract, timing decides everything. If your invoice was issued before April 1 but paid after, check the official transitional guidance before assuming which rate applies.

Two mistakes come up constantly. The first is defaulting to your home province’s rate out of habit, even when the customer is clearly located elsewhere. The second is failing to document payment timing during a rate change, which leaves you guessing (or worse, guessing wrong) if the CRA ever asks questions. Keep dated records: invoice date, payment date, and delivery or service completion date, every time.

Where can you verify the current rate yourself?

Don’t take a blog post’s word for it, including this one. The rate can shift, as Nova Scotia’s recent change shows, so build a habit of checking primary sources before you finalize an invoice or set up a new billing system.

Three places to check:

• CRA’s GST/HST calculator: Punch in a province and get the current combined rate along with the federal/provincial breakdown in seconds.
• CRA’s charge-and-collect page: Offers worked examples for goods, services, and real property if your situation is more complicated than a straightforward sale.
• Provincial government pages: Ontario’s own site confirms its 13% rate and lists point-of-sale rebates; other provinces publish similar pages when their rates change.

A quick way to confirm a rate in under a minute: open the CRA calculator, select the destination province from the dropdown, and the tool returns the current HST or GST/PST breakdown instantly. Bookmark it if you invoice across provinces regularly.

For ongoing updates, CRA publishes notices whenever a province’s rate changes, similar to the Nova Scotia transitional rules issued ahead of the April 2025 reduction. Subscribing to CRA’s business tax updates, or simply checking before every quarterly filing, saves you from discovering a rate change after you’ve already invoiced at the wrong number.

A practical note for Nova Scotia businesses selling into Ontario

If you run a small business in Halifax, Dartmouth, or anywhere else in Nova Scotia and you sell to Ontario customers, the biggest risk isn’t complexity. It’s assumption. Business owners often assume their home province’s rate applies everywhere, and that assumption gets expensive fast when the CRA reviews your filings and finds you’ve overcharged or undercharged HST on cross-border sales.

The Nova Scotia rate reduction in April 2025 is a useful reminder of how quickly this can go sideways.

You should bring in professional help when you notice any of these signs: your point-of-sale or invoicing software still charges the wrong rate for out-of-province sales, you’re unsure how to handle a contract that started before a rate change and finished after, or your bookkeeping hasn’t been reconciled since the last time rates shifted. These are exactly the situations where a small error compounds over a fiscal year.

Before you contact an accountant, gather a few basics: your last four quarters of HST returns, a sample of invoices to out-of-province customers, and your current point-of-sale or invoicing system settings. Having these ready turns a vague “something feels off” into a focused conversation your accountant can act on immediately.
