A review of the 2025 NTP season via the first CSSL Annual Report
The first-ever CSSL Annual Report is now available, covering the 2025 season. You can find it here.
The CSSL Annual Report covers the activities of the CSSL and the 'Northern' projects under its umbrella, including the Northern Tornadoes Project.
You'll see in the report that two tornadoes have been added to the 2025 total, both occurring in northwestern Ontario. The tornado at Big Sandy Lake in July was rated EF1 while the tornado at Keefer Lake in August was rated EF2. Both assessments were based on damage to trees.
A revised map of Canadian tornadoes in 2025 is below, or you can explore the map using the NTP's main dashboard here.
