Every year, Ontario gets its fair share of tornadoes and this year is proving to be no exception.
A powerful thunderstorm that ripped through the region at the end of April caused moderate damage in some communities. After further investigation, Environment Canada confirmed the first tornado hit Fergus, Ontario on April 27, 2011.
This season's first storm had winds of up to 110 km/h and was rated as F0 on the Fujita Scale.
On average, Ontario gets 12 tornadoes each season. The summer severe weather season runs from late April to early October.
People are urged to prepare for severe weather to try and avoid any significant damage or destruction. Emergency experts say a 72 hour safety kit is a crucial first step to prepare for the active weather season.
