Report an Adverse Event

Report an Adverse Event

If you’re using health products and you suspect you’ve developed a side effect as a result, you should report this event to Health Canada. You can do this by:

  • Visiting Adverse Reaction Reporting for information on how to report online, by mail or by fax
  • Calling 1-866-234-2345 (toll-free)


Contact your healthcare professional directly if you need medical support to help manage a side effect; the Canada Vigilance Program does not provide medical advice.
