A few updates:

From Sep 2 storms in ON
- The NTP survey team documented an EF1 downburst in the Brodhagen area, and we now have evidence that tornadoes likely occurred in the Bamberg and Tavistock areas. The survey team will be back out investigating these and other damage areas tomorrow.
- The NTP has determined that damage at Toronto and Orr Lake was caused by downbursts, ratings still to be determined.

From Sep 3 storms in ON
- It appears likely that the damage being reported in east Windsor is due to a tornado, and a survey team will visit tomorrow to confirm that.
- There is damage in a few other areas of Essex and Kent Counties that will also be investigated tomorrow.

The NTP has confirmed four tornadoes in Manitoba and Saskatchewan on August 30. Three tornadoes occurred in Manitoba, including an EF1 at Kola, an EF1 at Elkhorn and a second EF0 tornado at Elkhorn.

Ratings were determined via NTP ground and drone surveys. The Saskatchewan tornado occurred at Maryfield and caused no damage, so an EF0-Default rating was assessed.

09/03/2026

An active storm day in parts of southern ON with most damage being reported from about Bayfield to Cambridge. Some of the damage is significant (e.g. barn destroyed).

It appears the damage is mostly due to straight-line winds, but it’s possible that there was a tornado or two involved.

A damage survey team will leave WesternU in the morning to investigate.

Note that there are a couple of images being passed around online that are supposed to show observed tornadoes in Guelph and Paris but we believe these could be AI fakes. These are becoming increasingly prevalent in storm situations.

There was also some damage reported in the North York area of Toronto, and near Barrie at Orr Lake.

Results will be posted when available.

The NTP has confirmed that two tornadoes occurred in eastern PEI today, Aug 26. The first was observed at Little Harbour and caused EF0 tree damage there. The second followed shortly after at Rollo Bay, occurring entirely over water (i.e. a waterspout). An EF0-Default rating was assigned since no damage was reported.

More details will be provided for these two tornado events tomorrow.
