Fire Underwriters Survey™ (FUS™) is a national organization administered by SCM Opta Information Intelligence LP, formerly CGI Insurance Business Services, formerly the Insurers’ Advisory Organization (under the Insurance Bureau of Canada) and Canadian Underwriters Association. FUS provides data on public fire protection for fire insurance statistical work and underwriting purposes of subscribing insurance companies. Subscribers of Fire Underwriters Survey™ represent approximately 85 percent of the private sector property and casualty insurers in Canada. The overall intent of the fire insurance grading system is to provide a standardized measure of the ability of the protective facilities of a community to prevent and control the major fires that may be expected to occur by evaluating in detail the adequacy, reliability, strength and efficiency of the protective facilities and comparing the level of protection against the level of fire risk in the built environment. The fire insurance grading system used does not consider past fire loss records but, rather, fire potential based on the physical structure and makeup of the built environment.
