Where T1A Sits — and What That Changes at the Till

T1A covers ground within about 1 km of the centre of Medicine Hat — one of 3 forward sortation areas the city is split across, each carrying the same 5% but covering very different retail. Its closest postal neighbours are T1B (Medicine Hat) about 1 km off and T1C (Medicine Hat) about 4 km off.

The nearest postal area we hold in another province is S0N (Maple Creek / Shaunavon, Saskatchewan), about 140 km from T1A. A $500 order delivered into T1A carries $25.00 in GST; the same order delivered into S0N carries $55.00 in GST + PST — $30.00 apart on one invoice. Because Canadian sales tax follows the customer, a seller in Medicine Hat shipping to both charges 5% on the first and 11% on the second, from the same warehouse on the same day.

T1A is dense urban ground — a single neighbourhood inside one postal area — and density changes the taxable mix rather than the rate. Prepared food, personal services and in-person retail dominate what is rung through Medicine Hat codes like this one, all of it at 5%, while the zero-rated grocery basics that anchor a suburban shop are a smaller share of the total than the province-wide averages suggest.

The 5% above is set for the whole of Alberta and does not move between postal codes — T1A pays exactly what every other Alberta code pays. The bill that does move is an overnight one. Alberta's 6% tourism levy applies on top of GST, and has done at that rate since 1 April 2026, so a $200 room night inside T1A carries $12.00 of it. It was 4% before that. The base is wider than the room rate: booking, service and administration fees, pet charges, cleaning and even smoking-in-a-non-smoking-room penalties are inside it. It runs out at 28 nights: once the same guest has stayed that long continuously the booking stops being transient accommodation, and the levy stops with it.

Everything above is particular to T1A; the rules that are not — registration thresholds, filing frequency, input tax credit recovery, point-of-sale rebates — are set for the whole of Alberta, and they live on the Alberta sales tax guide rather than being restated on T1A's page, where the calculator above is already locked to 5%.

Selling into T1A: What You Need to Register For

Alberta runs a GST Only system administered by Canada Revenue Agency (CRA), with a registration threshold of $30,000 (federal GST). Filing frequency, input tax credit recovery, point-of-sale rebates and the full registration walkthrough are set out on the Alberta sales tax guide — they are province-wide rules, identical for every postal code here, so this page links them rather than repeating them.

1. Charge the rate the address decides. A delivery into T1A is an Alberta sale, so charge 5% GST — your own address does not enter into it.
2. Show it the way Canada Revenue Agency (CRA) expects. The GST amount as its own line item.

Everything else about selling here — thresholds, filing frequency, ITC recovery, point-of-sale rebates, and the full province-by-province sourcing rules — is identical for every postal code in Alberta and is set out once on the Alberta sales tax guide and in the Alberta GST/HST calculator.
