- Ontario and New Brunswick each added a confirmed tornado in the past week, including an EF‑1 near Glencoe, Ontario.
- Alberta accounts for over half of Canada’s tornado tally this year, reflecting the Prairies’ typical share.

Overview of Canadian Tornado Activity in 2026
So far this year, Canadian meteorologists have confirmed at least 41 tornadoes touching down across the country, a figure that continues to climb as the heart of summer brings peak tornado season to much of the nation. The majority of these events have occurred in the Prairie provinces, where atmospheric conditions favor supercell development, but activity has also been noted in Ontario and the Atlantic provinces. The Northern Tornadoes Project (NTP) at Western University has been instrumental in verifying these events, using ground surveys, drone imagery, and public reports to confirm damage paths and estimate wind speeds. As the season progresses, experts anticipate the total will approach or exceed the long‑term average of roughly 65 tornadoes per year, especially if current atmospheric patterns persist.
Details on the June 25 Ontario EF-1 Tornado
On June 25, a strong thunderstorm swept through southwestern Ontario, producing an EF‑1 tornado near the community of Glencoe. The NTP confirmed the twister after conducting on‑foot inspections and aerial drone surveys, which revealed a damage track nearly 10 kilometres long. Estimated maximum winds reached 145 km/h, sufficient to cause notable structural damage to barns, trailers, homes, and a significant number of trees along the path. Fortunately, no fatalities were reported, but several residents experienced property loss and required assistance from local emergency services. The event underscores the importance of rapid damage assessment to improve warning accuracy and to provide data for future climatological studies.
June 26 New Brunswick Tornado Confirmation
The following day, June 26, a similar line of strong thunderstorms moved into southern New Brunswick, spawning a tornado that was captured on video by a resident roughly 25‑30 kilometres southwest of Moncton. The NTP announced the confirmation via its Bluesky channel, noting that the footage showed a visible funnel lofting debris into the air. While the agency has not yet released an official rating or wind‑speed estimate, the visual evidence indicates at least EF‑0 strength. Survey teams are expected to examine the damage corridor in the coming days to refine the tornado’s characteristics. This event adds to the growing tally for Atlantic Canada, a region that historically sees fewer tornadoes but is not immune to severe convective outbreaks.
Alberta’s Dominance in Canada’s Tornado Count
Alberta continues to drive the national tornado statistics, accounting for 21 of the 41 confirmed tornadoes recorded across Canada so far this year. This concentration aligns with climatological norms, as the Prairies typically generate about half of the country’s annual tornado activity due to the frequent collision of warm, moist air from the Gulf of Mexico with cooler, dry air descending from the Rockies. The province’s expansive, relatively flat terrain provides ample space for supercell storms to develop and persist, increasing the likelihood of tornado genesis. Meteorologists warn that as long as the prevailing jet‑stream pattern remains favorable, Alberta may see additional touchdowns before the season wanes.
Challenges in Detecting Tornadoes in Sparsely Populated Areas
Despite improved detection tools, a notable number of tornadoes likely go unobserved and unreported, particularly in Canada’s northern and remote regions where population density is low. The absence of witnesses, limited radar coverage, and fewer ground‑based observers make it difficult to confirm weak or short‑lived vortices. The Northern Tornadoes Project mitigates this gap by employing high‑resolution satellite imagery, drone reconnaissance, and crowdsourced reports to identify damage signatures that might otherwise be missed. By systematically scanning suspected tracks, the NTP aims to produce a more complete climatological record, which is essential for risk assessment, building code updates, and public safety planning.
United States Tornado Season Progress Toward 1,000
South of the border, the United States is experiencing a particularly active tornado year, with the National Weather Service having confirmed 930 tornadoes from California to Vermont as of June 28, 2026. This places the nation on track to surpass the symbolic 1,000‑tornado milestone before the season’s end, consistent with its long‑term average of roughly 1,200 touchdowns annually. The widespread geographic distribution of reports reflects the country’s diverse climatological zones, from the Plains’ classic “Tornado Alley” to unexpected outbreaks in the Midwest and even the Northeast. Forecasters attribute the high count to a series of strong troughs and low‑pressure systems that have repeatedly supplied the instability and wind shear needed for tornadic supercells.
Notable U.S. Events: EF-4 in Oklahoma and Illinois Surge
Among the confirmed U.S. tornadoes, the most intense thus far has been an EF‑4 that struck Enid, Oklahoma, on April 23, delivering devastating winds estimated in excess of 266 km/h and causing widespread destruction across the city and surrounding rural areas. Meanwhile, Illinois has emerged as an outlier, contributing nearly 20 percent of all tornadoes logged nationwide so far this year—a share far above its historical average. This surge is linked to a persistent jet‑stream configuration that has funneled moist, unstable air into the state, triggering repeated rounds of severe thunderstorms and tornado outbreaks. The concentration of events in Illinois highlights how regional atmospheric patterns can temporarily shift the typical tornado hotspot map.
Safety Guidance and Resources for Tornado Warnings
In light of the ongoing tornado threat, both Canadian and U.S. authorities emphasize the importance of preparedness. When a tornado warning is issued, individuals should seek shelter immediately in a sturdy building’s lowest interior room, such as a basement or an interior hallway away from windows. If outdoors or in a vehicle, the recommendation is to lie flat in a low‑lying ditch or depression, covering the head with hands. Staying informed through reliable sources—such as Environment Canada’s alerts, the U.S. National Weather Service, and local news outlets—is crucial. Additionally, the NTP’s real‑time maps and the Weather Channel’s tornado safety videos provide valuable visual guidance on what to do before, during, and after a tornado strike.
