Weekend storm spawned third tornado: Environment Canada

Neighbours help clean up a home devastated by a tornado in Teviotdale on Monday August 3, 2015.

Environment Canada says a third tornado has been confirmed as part of a series of storms that hit southern Ontario on Sunday night.

Tornadoes had already been confirmed in Teviotdale and Marsville, when a team was sent to investigate damage in Lebanon, which is southeast of Listowel and less than 20 kilometres from Teviotdale.

The forecaster has since confirmed an EF-2 tornado touched down in Lebanon, with winds from 180 to 220 km/h leaving a swath of damage five kilometres long by 50 metres wide.

Officials say the most significant damage included tilted grain silos, one with the top nine metres removed, a barn roof ripped off and a sailboat lifted into a line of trees. There was also minor damage to several homes.

The three confirmed tornadoes hit in quick succession on Sunday; in Lebanon around 8:55 p.m., Teviotdale around 9 p.m. and Marsville around 9:30 p.m.

The most significant damage has been reported in Teviotdale, where two homes suffered significant damage.

There was also serious damage in Lucknow, where straight-line winds caused by a downburst destroyed a riding stable, damaged vehicles and roofs and downed over 100 mature trees.

This confirmation marks the fifth tornado of the season in Ontario, which usually sees an average of 12 confirmed tornadoes annually.
