A major storm that brought heavy rain, wind and hail to southern Alberta in early August cost insurers an estimated $450 million, according to the Insurance Bureau of Canada.

The storm brings insurance payments from natural catastrophes to $4 billion in Alberta since 2011, according to Property Claims Services — a branch of the bureau which reports on damage once it reaches a threshold of $25 million, which is deemed a natural catastrophe by the insurance industry.

“While the frequency and severity of weather events have been rising across the country, Alberta has been hardest hit,” IBC spokesman Bill Adams said in a news release.

"What’s more is that we are not out of the woods yet. Alberta hail season traditionally runs through the end of September.”

The intense storm on Aug. 7 hammered Airdrie and surrounding areas, including Rocky Mountain House and Red Deer, with torrential rains and both golf ball- and tennis ball-sized hail.

"This storm damaged tens of thousands of cars and homes," Adams said. "As such, some insurers brought in claims staff from other provinces and the United States to help those affected and to process claims.”

“Claims adjusters, body shops and contractors continue to assess and repair damages. Anyone who was affected is encouraged to contact their insurance representative as soon as possible to begin the claims process.”

The bureau provided a list of natural catastrophes in Alberta and their estimated damage since 2011:

  • August 2014 – A severe wind, rain and hail storm resulted in $450 million in insured damage in Airdrie and surrounding communities.
  • June 2013 – Severe weather events including the flooding in southern Alberta caused more than $1.7 billion in insured damage.
