The Canadian Electrical Code
requires that any residence, that is 80m squared or smaller excluding the basement, be 60 amp rated. Because of the fact that these homes were built a long time ago, and passed their electrical inspections at that time, they are whats called "grandfathered". This means that what exists, can exist, except now , the insurance companies, the underwriters have decided, that if you sell your house, the house must be upgraded to 100 amp, before they will assure insurance to the new buyers. Now this concerned me, because if the house was not insurable, then the mortgage broker can not issue a mortgage, catch 22.
In 2014, I called the Insurance Bureau of Canada
and spoke with a Mr. Roy Dickson, a statistician for the IBC. I asked the question, why has the IBC chosen to enforce the upgrading of the electrical service from 60 to 100 amps. His response to me was "to reduce the risk of claim". So I took the conversation one step further and asked the next question, "how many fires in Canada, have there been relating to 60 amp electrical services over the last 10 years"?. His response to me was "none".
