2026 PLANTING GUIDE

Canada Planting Season 2026

Province-by-province planting dates — when to start seeds, transplant, and direct sow across Canada this year.

Canada's 2026 planting season spans four months and eight time zones — from late February on Vancouver Island to late May on the Prairies. The single most important date for every Canadian gardener is their last spring frost. Everything else — when to start seeds indoors, when to transplant tomatoes, when to direct sow beans — flows from that one number.

This guide gives you the 2026 planting window for every major Canadian province, with specific dates for starting seeds indoors, safe transplanting of tender crops, and direct sowing cool-season vegetables. Use it alongside the frost date calculator to get the exact dates for your city.

British Columbia

Zones 4–8 | Longest season in Canada

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

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

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

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

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.

Atlantic Canada

Nova Scotia, New Brunswick, PEI, Newfoundland | Zones 4–6

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.
