Overdose Monitoring, Alert and Response System (OMARS)


An overdose is a medical emergency. If you are experiencing an overdose, CALL 911.

This site is for people to report overdoses and adverse reactions to drugs in Waterloo Region so community partners in Waterloo Region can better respond to these events. 

OMARS is an overdose, monitoring, alert, and response system developed by community partners in Waterloo Region who are concerned about reactions to drugs. The system seeks to collect information on overdose events. This information will be used to identify trends in accidental drug overdoses, provide alerts to the community about toxic drugs in circulation, and to respond with efforts that aim to reduce deaths and injuries.

No personal information will be collected on this site. Please do not use names or include any information that could identify you or others in your answers. The report will take about 5 minutes to complete and you can skip any questions you do not want to answer. Please fill out as much information as possible. It is okay if you don’t answer every question.

To report yours or another person’s overdose/reaction, scroll down and click “Start”. By clicking “Start” you agree to participate.
Thank you for participating!
