Canada Vigilance adverse reaction online database

Starting November 2018, the Canada Vigilance Adverse Reaction Online Database will be refreshed with data monthly. The time period of the data will remain 3 months behind, in order to account for data entry and quality control activities.

The Canada Vigilance Adverse Reaction Online Database contains information about suspected adverse reactions (also known as side effects) to health products.

Adverse reaction reports are submitted by:

  • consumers and health professionals, who submit reports voluntarily
  • manufacturers and distributors (also known as market authorization holders), who are required to submit reports according to the Food and Drugs Act.


This database includes data from 1965 to 2018-11-30. Information about  vaccines used for immunization has been included in the database since January 1, 2011. Information about human blood and blood components has been included in the database since September 1, 2015.

The database should not be used on its own to evaluate a health product's safety profile as It does not provide conclusive information on the safety of health products. It should not be used as a substitute for medical advice. If you have a medical concern, consult a qualified health professional. For more information consult our Interpretation of suspected adverse reaction data page.

For general questions about the content of the Adverse Reaction Online Database or for technical support, please contact the Canada Vigilance Program.
