Ontario Automated External Defibrillator (AED) Registry

The government is committed to increasing access to AEDs in communities across the province.  This centralized, online registry provides Ontarians and Emergency Medical Services (EMS) personnel with information about where these life-saving devices are located in their own communities.  

AEDs will be registered voluntarily by EMS personnel operating in municipalities and First Nations across the province.  As such, the Ontario AED Registry ("the Registry") will be updated on an ongoing basis each year and is expected to grow as more communities participate.

Quick Facts

  • A defibrillator gives an electrical shock to the heart to reset a normal beat. It scans for abnormal heart rhythms and advises the first responder to administer the jolt. Receiving immediate treatment could save lives and reduce the need for long-term hospitalization.
  • Early intervention using a defibrillator, together with CPR, can save lives and improve survival rates by up to 50 per cent.
  • Ontario passed the Chase McEachern Act in 2007 which provides liability protection to individuals who attempt to use a defibrillator in an emergency and to property owners and tenants.

Note : The Ministry of Health and Long-Term Care will continue to review and update the Registry with information about AEDs in communities across Ontario as additional information is provided by participating municipalities and First Nations. As of October 31, 2013, with the exception of information pertaining to the City of Toronto, the Registry includes only those AEDs that have been publicly funded by the government and does not include devices that have been privately funded or donated through other non-government sources.
