Three tornados that previously went unreported have been identified in northwestern Ontario.

The Northern Tornado Project (NTP) identified the storms through a year-end review of high-resolute satellite imagery to spot areas of wind damage that may have been missed.

The review determined twisters touched down southeast of Sachigo Lake in 2018, north of Silver Dollar in October 2022 and south of Windigo Lake in June of 2021.

All three touched down in wood areas and rated as having moderate intensity.

The storm that struck near Sachigo Lake was spotted near Misiwaweya Lake with wind speeds of 170 kilometres an hour and went about eight kilometres.

The Northern Tornado Project states the one near Silver Dollar struck near Young Lake on October 24, 2022, with wind speeds of 145 kilometres an hour and covered 20 kilometres.

The one near Windigo Lake happened on June 6, 2021, and tracked four kilometres with wind speeds of 145 kilometres an hour.

The NTP identified 33 other tornados that touched down elsewhere in Canada as far back as 2017.

This added nine to the total for 2023, 12 for 2022, 6 for 2021, 2 in 2020, 2 in 2019, 4 in 2018 and 1 in 2017.
