Atlantic Canada
March in Atlantic Canada is when winter grudgingly yields to spring. The equinox on March 20 marks the official start of spring, but winter often lingers. After the 20th, daylight outlasts darkness, yet cold weather can hang on. As a shoulder season month, March can bring some of the region’s biggest snowstorms.
Coastal areas see plenty of fog as cool land temperatures meet warmer maritime air. With average highs from -3 to +2, March offers surprises—winter’s final act before spring’s long-awaited return.
Quebec
An early spring is expected for Quebec in March 2026! The equinox on March 20 signals the season’s start and a warming trend just before the shift. Yet winter isn’t quite done. Expect mild days mixed with winter blasts, with snow still the main form of precipitation. Quebec can see up to 50 cm of snow during March, and powerful storms are always possible.
Daytime temperatures range from -2 to +3, with nighttime lows dipping to -6 to -9. Intense weather is common; March blizzards can disrupt life— like in 1971, when 47 to 80 cm of snow blanketed the province in a single storm.
Ontario
Ontario is vast, and so is its March weather. Southern Ontario begins to thaw while the north stays locked in winter. Early in the month, lake-effect snowstorms can dump snow quickly, often with little warning. The Great Lakes stir up fog and freezing rain, making March a prime month for ice storms.
In 2016, a freezing rain event coated parts of the GTA and Niagara in thick ice for 24 hours — a reminder that winter’s grip can linger. Temperatures vary widely; Toronto sees highs from +5 to +7, but in northern Ontario, including Thunder Bay, readings often remain below freezing.
The Prairies
March on the prairies is a slow dance between winter’s retreat and spring’s approach. By the end of the month, warmer days above freezing become more common in southern Saskatchewan and Manitoba. Southern Alberta typically warms earlier thanks to Pacific air descending from the Rockies. Meanwhile, northern areas stay firmly in winter’s grip. March is known for strong snowstorms, pushed by jet streams or storm tracks crossing the northern U.S. and feeding moisture into Canada. These systems bring heavy snow and blustery winds — like the historic blizzard of March 4, 1966, when temperatures plunged to -30 and winds howled at 90 km/h across the southern prairies.
British Columbia
March in British Columbia is all about contrast. On the coast, it’s mostly rain — Vancouver expects nearly 300 mm this month. Inland is much drier, with around 40 mm, though higher elevations still receive regular snowfall. In the north, it remains full winter, with snowstorms continuing into March. Late winter and early spring storms bring avalanche risks, especially in mountain areas. Coastal mornings are often foggy, and the province stays largely cloudy. As spring officially arrives on March 20, temperatures begin to rise: Vancouver averages +11, Kelowna hits +9, and Prince George stays cooler around +3.
Yukon and Western Northwest Territories
In the North, March brings a slow transition from deep winter toward something close to spring. The March 20 equinox tips the balance toward more daylight, but the warming trend is gradual. Yukon’s daytime highs hover around -5, while Yellowknife stays colder, with highs near -10. Winter conditions dominate, and all precipitation continues to fall as snow, adding to substantial snowpacks. On calm, clear nights, you might catch a uniquely northern phenomenon: radiation fog settling quietly into the valleys, casting a quiet, ghostly veil over the landscape.
Eastern Northwest Territories and Nunavut
Spring may arrive on the calendar on March 20, but in eastern Northwest Territories and Nunavut, winter still has the upper hand. However, March does bring hope:. In Iqaluit, average temperatures rise by about +7 through the month; in Yellowknife, the gain is closer to +10. Even with this boost, daytime highs remain well below freezing. March tends to be a dry month, with only light snowfall expected. Still, storms and blizzards can roll in, with fierce winds and whiteouts, and potential wind chills in dangerous territory.
Longer daylight hours and clearer skies help lift spirits, though, offering a glimpse of the season to come. March in the North may be harsh, but it signals that spring is inching closer — one snow-crunching step at a time.
