SAR Statistics Ø 8000 cases Ø 1100 of these would be classified as distress incidents Ø 3000 lives saved Ø 80 lives lost Ø 21, 000 persons assisted Canadian Coast Guard
Canada’s Search Effort • The Canadian Aeronautical and Maritime SAR system averaged a total of 4, 300 hours* per year of actual searching • The time spent searching over the last decade totals a staggering amount of over 47, 300 hours - the equivalent of almost 5 years of search effort for a single unit *This does not include transit times to and from an incident Canadian Coast Guard
Effectiveness • 92. 7 of all lives at risk were saved • Only 9 percent of all search and rescue (SAR) cases involved some sort of searching • 75% of all incidents involving the loss of life involved some sort of attempt to locate the distressed persons Canadian Coast Guard
Type of Incidents Involving Searching Canadian Coast Guard
Success • Typically if one is searching for something, success is achieved when it is located – If we were to use this measure of success alone, Canada achieved this 91% of the time • In the SAR world, success is only achieved when we find the search targets AND they are rescued, alive and well – Using this measure of success Canada only achieved a success rate of 79% when we were required to search Canadian Coast Guard
Cost • Using variable costs (fuel and proportional O&M) of each unit searching we can estimate the expenditure that was required in 2003 to conduct the searches. Canadian Coast Guard

Any investment in the technology for the definition of where, and how to search would result in the reduction of time, costs and ultimately increase the saving of lives Less Search, More Rescue Canadian Coast Guard
