It was the strongest tornado to hit Ontario in over 15 years.
It damaged roughly 100 houses and 25 other buildings, leaving a damage bill of about $130-million.
It also claimed one life and affected the lives of an entire community, effects that linger 10 years later.
On August 21, 2011, an isolated supercell thunderstorm that formed and gained strength over Lake Huron, came ashore in Goderich as an F-3 tornado.
In this episode of the 519 Podcast, we look back at that fateful day in Goderich, what has happened since, and how the community is doing now.
