Ontario Automated External Defibrillator (AED) Registry

The government is committed to increasing access to AEDs in communities across the province.

The Automated External Defibrillator (AED) Registry is being updated and is unavailable at this time. In case of a health emergency, please call 9-1-1 or go directly to the emergency department of your nearest hospital.

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.
