Vegetable Growing Guides for Canada
Canada's gardens run from zone 2 to zone 9, and the frost-free season ranges from about 90 days in the North to 222 on the Pacific coast. Every guide below starts from the same question: does this crop actually fit the season you have?
Find your growing band
| Band | Where | Last spring frost | First fall frost | Frost-free days |
|---|---|---|---|---|
|
Long season Zones 7-9 |
Pacific Coastal Mild (Vancouver Island, Lower Mainland); Inland Valleys & Southern Lakes (Okanagan, Golden Horseshoe, Niagara) | late March on the coast (Vancouver ~28 March); early-to-mid May inland | early November on the coast; mid-to-late October inland | 150-222 frost-free days |
|
Medium season Zones 4-6 |
Central Continental (Ottawa Valley, Montreal, Quebec City); Atlantic Maritime (Nova Scotia, PEI, Newfoundland coasts) | Toronto ~20 April to 10 May; Montreal ~3 May; mid-to-late May inland | late September to mid-October | 130-170 frost-free days |
|
Short season Zones 2-3 |
Prairies (Calgary, Edmonton, Saskatoon, Winnipeg); Far North & Alpine | Edmonton ~7 May; Calgary ~23 May; Winnipeg ~25 May, later at elevation | early-to-mid September | 90-130 frost-free days |
Long season: The only part of Canada where overwintering vegetables outdoors is routine rather than experimental. Medium season: Long enough to ripen tomatoes and peppers from indoor starts, but days-to-maturity has to be checked against the season, not assumed. Short season: Long summer daylight partly compensates for the short calendar, but short-season cultivars and season extension are not optional.

Frequently Asked Questions
How do I know which Canadian season band I am in?
Find your local last spring frost and first fall frost dates and subtract. Roughly 150-222 frost-free days is the long band, 130-170 the medium band, and 90-130 the short band.
Why do Canadian guides start with days to maturity?
Because season length is the binding constraint here. A crop that needs more days than your season provides will not finish, however well you grow it. Checking the arithmetic first avoids the most expensive mistake.
How many crops do these guides cover?
20 vegetables, each checked against Canadian frost dates, with season extension advice and short-season cultivar guidance.
