Coastal valleys around Victoria and Vancouver hold Canada's mildest winters. Gardeners here extend the season well into November and start cool-season crops by late February. Drainage and rainfall management tend to matter more than frost protection.
The Great Lakes moderate temperatures significantly. Windsor and Niagara sit in Zone 7, while Ottawa and Montreal are Zone 5. Last frost dates separate by three weeks or more between zones. Clay-heavy soils across much of southern Ontario benefit from generous organic matter each spring.
Short, intense summers with low humidity define gardening on the Prairies. Planting windows compress dramatically — Regina and Saskatoon gardeners often have fewer than 110 frost-free days. Windbreaks and cold frames extend the practical growing season by several weeks on either end.
Maritime climates bring reliable moisture and moderate temperatures to Nova Scotia, PEI, and New Brunswick. Fog and humidity favour brassicas and root vegetables. Gardeners contend with salt spray near the coast and heavy clay soils inland.
