Canadian Coast Guard SAR Statistics  8000 cases  1100 of these would be classified as distress incidents  3000 lives saved  80 lives lost  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 searchingThe 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 unitThe 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 Type of Incidents Involving Searching

Canadian Coast Guard Success Typically if one is searching for something, success is achieved when it is locatedTypically 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 wellIn 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.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.
