Data on location and frequency of serious injuries on Toronto roadways are analyzed to proactively identify locations of possible safety concerns where efforts should be focused. Small factors such as size and speed of vehicle, age of person being hit, weather and lighting can be the difference between a serious injury and a fatality. 
Killed or Seriously Injured (KSI) data displayed below has a delay from date of occurrence to being officially verified and reported. For fatalities the usual time period for data to display accurately on the table is 1-2 weeks and for seriously injured 2-3 months. Other factors can also contribute to inaccurate data being displayed, if you believe there is a data error after the time periods above have elapsed please email email@example.com
 Starting in 2014, the Toronto Police Service made amendments to collision reporting practices that made the criteria for reportable collisions stricter, likely resulting in less reported collisions. For this reason, there may be inconsistencies in data between years prior to 2014 and those after.
