The impact of the Harmonized Sales Tax (HST) on Ontario and B.C. property and casualty insurers' reserves in 2009 -- estimated to be $268 million -- is equivalent to that of a large catastrophic loss, according to the Insurance Bureau of Canada (IBC).
Barbara Sulzenko-Laurie, IBC's vice president of policy, noted the effects of the HST in slides she presented at the 2010 Swiss Re Breakfast in Toronto.
Her remarks were part of a wide-ranging discussion on the broader state of the Canadian P&C insurance industry in 2009.
One IBC slide showed a number of projected effects of the HST on Ontario and B.C. insurers between 2010 and 2015.
For example, retail sales tax (RST) on claims and operating costs for Ontario and B.C. insurers in 2010 is projected to total $436 million.
But add an additional $34 million in operating expenses due to the HST, as well as an extra $83 million in claims costs due to the HST, IBC figures show.
