About Ontario Sales Tax
Ontario has a 13% combined sales tax rate, consisting of the 5% federal GST and 8% provincial HST.
Ontario uses the Harmonized Sales Tax (HST) system. The HST combines the 5% federal GST and the provincial portion into a single streamlined rate administered entirely by the Canada Revenue Agency. Businesses file one return, claim one set of input tax credits (ITCs), and remit to one authority — significantly simplifying compliance compared to dual-tax provinces.
What Postal Code L3K Covers
L3K covers Port Colborne at the Lake Erie entrance to the Welland Canal, where Lock 8 — among the longest canal locks in the world — regulates vessels entering the system. The West Street promenade alongside the canal forms a compact restaurant and shopping strip built around ship-watching traffic. Nickel Beach and the Sherkston shoreline draw substantial summer visitor volume to an otherwise small industrial town.

Where L3K Sits — and What That Changes at the Till
L3K sits about 30 km south of St. Catharines, the nearest centre of any size, and is the only postal area our data records for Port Colborne. Its closest postal neighbours are L3C (Welland) about 10 km off and L3B (Welland) about 10 km off.
The nearest ground where the rate changes is about 370 km away — J0X in Quebec, at 14.975%. That distance is the useful part: nothing bought or delivered in L3K is a borderline case, so the only rate question worth asking here is whether the sale is taxable at all, not which province's number applies to it.
The Rainbow Bridge at Niagara Falls lies about 25 km from L3K, which puts US retail inside an ordinary afternoon. What comes back is a customs question rather than a provincial one, and the thresholds are unforgiving: no personal exemption at all on a same-day trip, CAD 200 once you have been away 24 hours — lose it by a dollar and duty and tax apply to everything you are carrying, not just the excess — and CAD 800 after 48 hours, where only the amount over the line is assessed. Because Ontario is an HST province, the CBSA collects the full 13% at the booth rather than the 5% federal portion alone.
Port Colborne anchors a mixed code serving about 20,000, so spending here runs to fuel, groceries and trades work rather than dense storefront retail. Trades invoices are where HST errors cluster in a code like L3K: labour and materials are taxed the same way, but only the materials leave the contractor with a recoverable credit. Traffic through Sugarloaf Harbour Marina shows up in the local mix as fuel, prepared food and accommodation rather than durable retail — categories where the rate is the same 13% but the separate municipal levies are not. Around Nickel Beach, demand is seasonal, and seasonal demand is where the small-supplier threshold bites hardest: an operator who only trades in summer can cross $30,000 inside a single quarter and owes HST from the sale that took them over it, not from the following year.
The 13% above is set for the whole of Ontario and does not move between postal codes — L3K pays exactly what every other Ontario code pays. Overnight accommodation is where Port Colborne parts company with them. The city levies a 4% Municipal Accommodation Tax on top of HST, so a $200 room night inside L3K carries $8.00 that the identical room would not carry in an Ontario municipality that never adopted one. It runs out at 31 nights: once the same guest has stayed that long continuously the booking stops being transient accommodation, and the levy stops with it. By-law 7283/105/24 exempts the city's own residents unless they choose to stay overnight locally, and left every booking made before January 2025 alone.
Everything above is particular to L3K; the rules that are not — registration thresholds, filing frequency, input tax credit recovery, point-of-sale rebates — are set for the whole of Ontario, and they live on the Ontario sales tax guide rather than being restated on L3K's page, where the calculator above is already locked to 13%.

Frequently asked questions
Quick answers to the most common questions users ask.
What areas does postal code L3K cover?
The Forward Sortation Area L3K covers Port Colborne, Sherkston and Humberstone in the Niagara Region region of Ontario, serving about 20,000 in a predominantly mixed setting. Retail and civic landmarks inside the code include Welland Canal Lock 8 (one of the world's longest locks), Nickel Beach, Sugarloaf Harbour Marina and West Street promenade — the places where purchases in L3K actually happen.
What is the sales tax rate for FSA L3K in Ontario?
The combined sales tax rate for postal code FSA L3K in the Port Colborne area of Ontario is 13%. This is a Harmonized Sales Tax (HST) that combines the 5% federal GST with an 8% provincial component into a single rate administered by the Canada Revenue Agency.
How do I calculate tax for a purchase in Ontario (FSA L3K)?
To calculate the total price including sales tax for any purchase in Ontario, multiply the purchase price by 1.13. For example, a $100.00 purchase costs $113.00 total, with $13.00 in sales tax.
For the reverse calculation, divide the total price by 1.13 to find the pre-tax amount. Run the example above backwards and $113.00 paid in Ontario resolves to $100.00 before tax and $13.00 of HST.
Does Ontario use HST or separate GST and PST?
Ontario uses a Harmonized Sales Tax (HST) system. The HST combines the 5% federal GST with the 8% provincial component into a single rate of 13%. Businesses file one return with the CRA.
What kind of area is L3K — urban, suburban or rural?
L3K is a predominantly mixed code serving about 20,000, within the Niagara Region region. That mix means both in-store and delivered purchases are common, and delivered orders take the rate for this postal code rather than the seller's.
Do local taxes in L3K change what I pay?
Not the sales tax itself — Ontario levies 13% province-wide and there is no municipal sales tax in Canada. What can differ by municipality are the separate levies that sit outside sales tax: accommodation and lodging taxes on short-term stays, and in some provinces local levies on prepared food or alcohol.
So a hotel folio or restaurant bill from Port Colborne can total more than 13% while a retail receipt from the same street does not. Check the municipality's own schedule for those, and see the Ontario sales tax guide for the province-wide rules.
How does FSA L3K map to a sales tax rate?
The Forward Sortation Area (FSA) is the first three characters of a Canadian postal code. L3K falls within the range assigned to Ontario, specifically the Port Colborne area. Canada sets sales tax provincially rather than municipally, so the FSA's job here is to place the buyer: once you know a delivery address sits in L3K, you know it is an Ontario sale and you charge 13%. That matters most for shipped orders, where the buyer's postal code — not your own — decides the rate.
