Supporting People in Extreme Cold Who Use Substances

Cold weather events can be challenging for anyone trying to stay warm and safe. People who use substances are particularly at risk, due to the physical effects of some substances. They may also be impacted by other risks during extreme cold, such as homelessness or a lack of appropriate clothing.

This page summarizes key messages and services in the City of Thunder Bay to support people who use substances in extreme cold weather. It was adapted from the Ontario Harm Reduction Distribution Program resource, Supporting Individuals During Extreme Cold Events, 2024.

NOTE:
Service access and other information can change. Please reach out to organizations first when possible. This page will be reviewed and updated monthly throughout Winter 2025/26. If corrections or changes are needed, please email the Harm Reduction Program.
