Best POS for a grocery store in Toronto

Last reviewed 2026-08-05 · by the RetailPOS team

In short
For a Toronto grocery store, the best POS handles PLU codes and sold-by-weight with a scale, scans fast for high throughput, and gets the tax right: in Canada most basic groceries are zero-rated (0%), while snacks, prepared foods and non-food items carry 13% Ontario HST — so a single basket mixes taxable and zero-rated lines. RetailPOS supports PLU, weight and per-item tax classes with multi-store on every plan. The checklist below is what decides it.

An independent grocer in Scarborough and a small multi-branch operation across the GTA need the same core: weight-based selling and correct mixed-basket tax at speed. Here is what to look for in Toronto, and where RetailPOS fits.

What a Toronto grocery POS must do

1. PLU & sold-by-weight. Produce and deli items priced by weight via a connected scale, with PLU lookup for fast entry.

2. Correct mixed-basket tax. Basic groceries are zero-rated in Canada; snacks, prepared hot foods, candy and non-food items carry 13% HST. The POS must apply the right tax class per item so a single basket rings correctly.

3. Fast scanning & throughput. High-volume barcode scanning with a responsive register so lines move.

4. Multi-store & stock. Central catalogue, per-store stock, transfers, and low-stock alerts for reorder.

5. Offline. Keep ringing if connectivity drops, then sync automatically.

Where RetailPOS fits — and where it doesn’t

Pick RetailPOS if you want PLU/weight selling, correct per-item tax classes and multi-store at flat per-shop pricing with your own processor.

Look elsewhere if you need supermarket-scale features — deli/scale label printing at department level, deep shelf-label and planogram management, or wholesale/DSD receiving — that dedicated grocery/supermarket systems specialise in. RetailPOS covers the independent-grocer workflow rather than large-format supermarket operations.

Frequently asked

Is there tax on groceries in Toronto?
In Canada most basic groceries are zero-rated (0% GST/HST), while snacks, candy, prepared/hot foods and non-food items carry 13% Ontario HST. The POS applies the right tax class per item; check the HST figure with the tax calculator (select Canada, HST Ontario) and confirm item categories with the CRA.
Does it work with a weighing scale?
Yes — items can be sold by weight with PLU lookup, so produce and deli lines ring at the correct price.
Can one receipt mix zero-rated and taxable items?
Yes — each item carries its own tax class, so a basket can mix zero-rated basic groceries with HST-taxable snacks and non-food items and total correctly.
