Environment and Climate Change Canada confirms three tornadoes and
two downbursts in Eastern Ontario on Friday, September 21. These
were from severe thunderstorms associated with a strong cold front.

A severe thunderstorm produced a downburst in Calabogie near 4:15 pm
Friday. A tornado then developed over Calabogie and tracked to White
Lake. Several houses have roof damage and many trees were snapped
and uprooted. Winds associated with this downburst and EF-1 tornado
are estimated to be up to 175 km/h.

The same severe thunderstorm then produced a second tornado that
tracked from 10 km west of Kinburn across Dunrobin and Gatineau
between 4:40 pm and 5:20 pm. This tornado damaged or destroyed
numerous buildings, overturned vehicles and snapped many trees and
hydro poles. There were also reports of multiple injuries including
several people that were critically injured. Preliminary assessment
of the damage indicates that this was a high end EF-3 tornado with
wind speeds up to 265 km/h.

Another severe thunderstorm produced a tornado which tracked from
the Arlington Woods to Greenboro areas in Ottawa near 6:00 pm. This
tornado significantly damaged buildings and snapped many trees and
hydro poles. Preliminary assessment of the damage indicates that
this was a high end EF-2 tornado with wind speeds up to 220 km/h.

Yet another area of damage from a severe thunderstorm was
investigated at Sharbot Lake. A downburst with maximum winds of
about 110 km/h knocked down many trees in the area.

Staff from Environment and Climate Change Canada, along with Western
University continue to survey and assess the damage to determine the
exact track of these tornadoes.

Any reports of damage can be sent to Environment and Climate Change
Canada by emailing or tweeting reports using
