Insured property losses from the recent northern Alberta wildfire are estimated at $C3.58 billion ($3.62 billion), more than twice the sum from Canada’s previous most costly natural disaster, according to the Insurance Bureau of Canada (IBC).

The Fort McMurray blaze started on May 1, leading to an evacuation order for the city.

The IBC says more than 27,000 property claims have been received at an average of $C81,000 ($81,992) and more than 12,000 auto insurance claims averaging $C15,000 ($15,184).

More than 5000 commercial claims have been made at an average of $C227,000 ($229,781).

“This wildfire, and the damage it caused, is more alarming evidence that extreme weather events have increased in both frequency and severity in Canada,” CEO Don Forgeron said.

“As a country we need to take a more disciplined and sustained approach to helping prepare Canadians for fire and floods.”

The cost of the wildfire has surpassed the 2013 southern Alberta floods, which cost $C1.7 billion ($1.72 billion) in insurance claims.
