Canada Planting Season 2026 — Dates by Region
Canada planting season 2026 — when each region opens for outdoor planting, by province and city. Indoor start dates, last frost dates, and safe transplant windows.
Canada's planting season 2026 spans nearly three months coast to coast. BC's coast opens in late March, southern Ontario in late April, the Prairies and Quebec around mid-May. The pivotal date in every region is the last spring frost — that's what determines when to transplant tomatoes outdoors, when to stop starting seeds indoors, and when your garden is genuinely safe. Below: last frost dates and planting windows for every major Canadian city, organized by province.

BC's coast has Canada's longest planting season — Victoria and Vancouver gardeners can grow cool-season crops like peas, spinach, and kale nearly year-round. Direct sow peas outdoors as early as February on the coast. The BC interior (Kelowna, Kamloops) has hot summers ideal for corn, peppers, and melons but cooler spring and fall. Northern BC has a Prairie-like short season.
BC planting season tip: Coastal BC gardeners can start a second round of cool-season crops (lettuce, spinach, kale) in late July for fall harvest — the mild fall extends harvests well into November.

Alberta
Zones 3–5 | Short but intense season
| City | Last Frost | Start Tomatoes Indoors | Transplant Outdoors |
|---|---|---|---|
| Calgary | May 23 | Mar 28 – Apr 11 | After May 23 |
| Edmonton | May 15 | Mar 20 – Apr 3 | After May 15 |
| Lethbridge | May 9 | Mar 14–28 | After May 9 |
Alberta's intense summer sun — long days with 17+ hours of daylight in June — partially compensates for the short season. Tomatoes, peppers, and corn grow quickly once established. Calgary gardeners are well served by short-season varieties (65 days or less for tomatoes). Start seeds indoors in late March to have robust transplants ready for late May.
Alberta planting season tip: Calgary is notorious for late-May and early-June cold snaps — keep frost cloth on hand even after your last frost date. The Chinook winds can warm things up dramatically, then temperatures drop overnight.
Saskatchewan & Manitoba
Zones 2–4 | Shortest season, hottest summers
| City | Last Frost | Start Tomatoes Indoors | Transplant Outdoors |
|---|---|---|---|
| Winnipeg | May 25 | Mar 30 – Apr 13 | After May 25 |
| Regina | May 21 | Mar 26 – Apr 9 | After May 21 |
| Saskatoon | May 20 | Mar 25 – Apr 8 | After May 20 |
The Prairies have Canada's shortest frost-free seasons — Winnipeg averages just 115–120 days — but also some of the hottest summer temperatures. This combination means fast-maturing varieties are essential. Choose tomatoes rated 65 days or less, and prioritize crops that thrive in heat: beans, corn, zucchini, cucumbers, and basil.
Prairie planting season tip: Direct sow cool-season crops (peas, spinach, lettuce, carrots) as soon as the soil can be worked in early to mid-May — well before your last frost date. These crops tolerate light frost and benefit from cool spring weather.
Ontario
Zones 4–7 | Most diverse conditions in Canada
| City | Last Frost | Start Tomatoes Indoors | Transplant Outdoors |
|---|---|---|---|
| Windsor | Apr 25 | Mar 1–15 | After Apr 25 |
| Toronto | May 9 | Mar 14–28 | After May 9 |
| Ottawa | May 10 | Mar 15–29 | After May 10 |
| Sudbury | May 22 | Mar 27 – Apr 10 | After May 22 |
| Thunder Bay | May 28 | Apr 2–16 | After May 28 |
Ontario spans a huge range of growing conditions. Windsor (Zone 7) has a near-US growing season and can grow sweet potatoes, peanuts, and melons reliably. Toronto and the Golden Horseshoe are among the best vegetable growing regions in Canada — long season, hot summers, mild falls. Northern Ontario is closer to the Prairies in terms of frost dates and variety selection.
Ontario planting season tip: Southern Ontario gardeners can plant garlic in late October for harvest the following July — one of the most productive and low-effort crops for the region. Plant in fall, mulch with straw, and harvest when the lower leaves turn brown.
Quebec
Zones 3–5 | Great summers, cold winters
| City | Last Frost | Start Tomatoes Indoors | Transplant Outdoors |
|---|---|---|---|
| Montreal | May 5 | Mar 10–24 | After May 5 |
| Quebec City | May 13 | Mar 18 – Apr 1 | After May 13 |
| Sherbrooke | May 17 | Mar 22 – Apr 5 | After May 17 |
Quebec's planting season is similar to Ontario's but with slightly colder springs and falls. Montreal is actually a surprisingly good growing city — the St. Lawrence Valley is warm, and urban heat island effects mean downtown Montreal gardens often outperform suburban ones. Quebec summers get genuinely hot (35°C+), which tomatoes and peppers love.
Quebec planting season tip: Quebec City and eastern Quebec gardeners should stick to short-season varieties for heat-loving crops. Montreal gardeners have more flexibility and can grow most of the same varieties as Toronto.

Nova Scotia, New Brunswick, PEI, Newfoundland | Zones 4–6
| City | Last Frost | Start Tomatoes Indoors | Transplant Outdoors |
|---|---|---|---|
| Halifax | Apr 20 | Feb 25 – Mar 11 | After Apr 20 |
| Fredericton | May 10 | Mar 15–29 | After May 10 |
| Charlottetown | May 14 | Mar 19 – Apr 2 | After May 14 |
| St. John's | Jun 2 | Apr 7–21 | After Jun 2 |
Atlantic Canada's coastal climate moderates temperatures — summers are cooler than the St. Lawrence Valley but milder than the Prairies. Halifax has a surprisingly early last frost for its latitude. PEI's deep red soils are excellent for root vegetables — the island is world-famous for its potatoes for good reason. Newfoundland (St. John's) has Canada's latest reliable last frost date among major cities.
Atlantic planting season tip: Coastal fog and cool summers in Atlantic Canada favour brassicas (cabbage, broccoli, kale) and root vegetables over heat-loving crops. Focus on cold-tolerant varieties and use row covers to extend the season at both ends.
