Can I run a single Magento store for all 13 provinces and territories?

Yes, and that’s what we recommend for most Canadian merchants. Magento 2’s multi-store-view architecture lets you serve all provinces from one backend with:

• One website, one store, two store views (en-CA + fr-CA) for the bilingual case
• Tax rules per ship-to province using the region field in the address, not separate stores
• Currency in CAD for the whole site, with optional USD switcher for cross-border DTC
• One product catalog, one checkout, one customer database

You only need multi-store (separate websites) if you want completely different product catalogs, currencies, or B2B vs B2C separation, and even then, often a single store with customer groups handles it. We’ll recommend the right architecture in the audit.
