The Insurance Bureau of Canada (IBC) says the heavy rain and strong wind that hit southern Ontario on June 22 caused an estimated $30 million in insured damage.
"Weather events that used to happen every 40 years can now happen every six years," IBC's Ontario VP Ralph Palumbo, said in a statement.
"In recent years, we've seen first-hand the impact that storms can have. Storms are more frequently damaging our homes and business properties."
The heavy rain caused localized flooding in cities across the region including London and Toronto.
In London, the rain overwhelmed the sewers, causing backups into the basements of homes and businesses, including White Oaks Mall.
Meanwhile in Toronto, flooding was mainly due to pooling water that caused road closures. There was also basement flooding in the Greater Toronto Area.
Across southern Ontario, strong winds toppled trees and combined with lightning, caused over 100,000 Hydro One customers to lose power.
IBC is encouraging homeowners to take steps to protect their property before the next big storm, and to ensure they understand their coverage and have the policies that will work best for them.
