2. Human Consequences<br />
Injury and fatality data reported in ORSAR tend to under report and misreport the<br />
extent of human consequences of motor vehicle collisions. This section discusses<br />
adjustments made in the raw data to better reflect the impacts on those involved in the<br />
collisions.<br />
a) Additional deaths reported by Coroner’s Office<br />
ORSAR lists 799 fatalities related to motor vehicle collisions in Ontario in 2004.<br />
These data are based on Motor Vehicle Accident Reports (MVAR) filed by police<br />
officers. On occasion, a MVAR may not be submitted by police or may be amended but<br />
too late for inclusion in the ORSAR. Also the cause of death may be determined only<br />
later to be a motor vehicle collision by the Coroner but this information may not be<br />
provided to ORSAR or may be provided too late to include in ORSAR.<br />
For 2004, the Coroner reports approximately 900 fatalities due to transportation<br />
related crashes, including HTA-reportable and non-reportable collisions, train and<br />
subway related incidents using a one-year cut-off instead of the 30-day limit imposed by<br />
ORSAR. Of the extra 36 motor vehicle collision fatalities reported by the Coroner, 21<br />
occurred within 30 days and of them 14, could be determined to be HTA reportable based<br />
on the weight of evidence. (The status of one case could not be determined.)<br />
As a result, 813 fatalities, or 1.02 times the number identified in ORSAR, are used<br />
in the model for 2004. The same factor will be used for subsequent years to reflect<br />
