"The Canadian Disaster Database (CDD) contains detailed disaster information on more than 1000 natural, technological and conflict events (excluding war) that have happened since 1900 at home or abroad and that have directly affected Canadians. The CDD tracks ""significant disaster events"" which conform to the Emergency Management Framework for Canada definition of a ""disaster"" and meet one or more of the following criteria:

•10 or more people killed

•100 or more people affected/injured/infected/evacuated or homeless

•an appeal for national/international assistance

•historical significance

•significant damage/interruption of normal processes such that the community affected cannot recover on its own

The database describes where and when a disaster occurred, the number of injuries, evacuations, and fatalities, as well as a rough estimate of the costs. As much as possible, the CDD contains primary data that is valid, current and supported by reliable and traceable sources, including federal institutions, provincial/territorial governments, non-governmental organizations and media sources. Data is updated and reviewed on a semi-annual basis"
