How Much Does an E-commerce Site Cost in Canada? (2026)

Short answer: A small Shopify store in Canada typically costs CAD $8,000–$20,000 to build, a custom or multi-integration store $25,000–$100,000+, and most stores also pay $50–$500 a month in platform and app fees plus payment processing of roughly 2.4%–2.9% + 30¢ per transaction.

1. The platform

Shopify plans start around CAD $39 per month and Shopify Plus starts near US $2,300 per month. WooCommerce is free software, but you pay for hosting, plugins and maintenance.

2. Design and build

A theme-based store is the most affordable. Custom design, a bilingual catalogue and a tailored checkout add cost but lift conversion. Expect most of the budget to go here.

3. Canadian essentials

Automatic GST, HST, PST and QST tax setup
Interac, credit card and wallet payments
Canada Post and Purolator live shipping rates
English and French product content and checkout

4. Integrations

Connecting inventory, accounting, ERP or point-of-sale systems can add $3,000–$30,000 depending on complexity.

5. Ongoing costs

Budget for platform fees, apps, security updates, support and marketing. A common rule of thumb is 10–20% of the build cost per year for maintenance and improvements.

How to keep costs under control

Launch with the features that drive sales first, choose proven platforms, and ask for a fixed-scope quote. A short discovery phase prevents expensive surprises later.
