Privately run insurance companies (i.e. not government run like ICBC) have a primary responsibility to generate profits for shareholders - its a business, not a charity. How do they do that ? Three ways.
(1) Charging a premium, calculated by an actuary, based on property value (home, car, motorcycle, boat, etc.), geographic location (are you in a high risk area ?) and perceived risk (are you a bad driver ?).
(2) Investing that money for reasonable return.
(3) Paying out as little as necessary for claims - that's why they have adjusters and appraisers, to insure that they are paying out what the insured is entitled to and no more.
The problems come in when (I'm sure F3800RC will correct me again if I'm wrong) when:
(1) the actuary over or underestimates the perceived risk. If they guess wrong premiums may go up or down- mostly up.
(2) If there's a financial crisis (think 2008/2009) and there's a negative return on investment and then premiums go up.
(3) There's widespread fraud in the claims system that adjusters and/or appraisers can't or won't deal with and then premiums go up.
Why is there such a disparity when you go shopping for insurance ? Why are there so many people driving and riding dirty ? Why should it be the insured's responsibility to guarantee they are being treated fairly ? I don't have the answers to these questions, which is why a provincial inquiry is necessary and long overdue.
Bottom line, IMHO, is that insurance companies are not your friends - they are businesses that must generate reasonable profit to keep the doors open BUT must be held accountable for the often arbitrary natures of their actions. Demand change from your provincial government.
