Regional Vegetable Gardening in Canada
Canada’s vegetable gardens run on frost dates. We use four regions, the same ones as our Canada planting calendar and month guides: south coastal BC, the Prairies, southern Ontario and Quebec, and Atlantic Canada.
Frost data are Environment and Climate Change Canada climate normals (1981–2010).
Find your region
| Region | Stations in the table | Average frost-free days |
|---|---|---|
| South coastal BC | Vancouver, Victoria, Abbotsford | 208–237 |
| Prairies | Saskatoon, Calgary, Edmonton, Winnipeg | 110–121 |
| Southern Ontario & Quebec | Toronto (Pearson), Ottawa, Montreal | 159–168 |
| Atlantic Canada | Charlottetown, St John'S, Moncton | 134–153 |
Frost dates, not zones, set the vegetable year
Canada’s plant hardiness zones describe how severe the winter is and are used for perennial plants that must survive it. For annual vegetables, the growing season is the frost-free period between the last spring and first fall frost, and each crop’s days to maturity must fit inside it.
Plan by month
Each month guide gives advice by region: see the Canada vegetable planting calendar, monthly and seasonal gardening in Canada and the Canada growing guides.
