Around April 13, the 30-year mean date of the last spring frost at Toronto, the official station 4 km from Toronto. Half of years see frost after the mean, so tender crops usually wait a week or more past it.

When can I plant tomatoes in Toronto?

Start seeds indoors around March 2 and transplant around April 20, once nights hold above 10 C. The full 32-crop table on the planner computes every window for Toronto.

How long is the growing season in Toronto?

About 203 frost-free days on average, from roughly April 13 to November 3. Crops whose days-to-maturity exceed that window need transplants, short-season varieties, or season extension.

How this page was made

Every date above is computed from the Environment and Climate Change Canada Canadian Climate Normals at Toronto: the 30-year mean dates of last spring and first fall frost, with crop offsets from standard horticultural practice. Full method and crop sources: data and methodology. These are planning averages, not forecasts: half of years frost later than the mean, so harden off transplants and watch the local forecast at the shoulders of the season.
