Most of Canada falls in zones 3–6. Cold-hardy crops like kale, carrots, beets, and potatoes grow across the country. Southern Ontario and BC support a much wider range.

What is the warmest zone in Canada?

Canadian Zone 9 — found on southern Vancouver Island and the Gulf Islands in BC — is the warmest, with near-frost-free winters and year-round growing potential.

Can you grow tomatoes in Canada?

Yes — tomatoes grow across most of southern Canada (zones 4–9) when started indoors 6-8 weeks before last frost. Short-season varieties work in colder zones.
