HARS Stocktake Survey - Request for interest from those working in extreme heat preparedness and response to participation

The NCCEH is conducting a survey to gauge the implementation status of Heat Alert and Response Systems (HARS) or HARS-like plans of all health authorities/units/zones, provinces, territories, and relevant agencies in Canada. The information gathered will allow the NCCEH and federal partners to better understand HARS implementation across Canada, uncover best practices for HARS across different regional contexts in Canada, and help shape future heat-related program and policy development. The data collected in this study is anonymous, and all responses collected will remain confidential.

Deadline for the survey is now extended to Friday May 31, 2024

If you are involved in extreme heat-related preparedness and response work at health authorities/units/zones, provincial/territorial (PT) governments or relevant agencies in Canada and would like to participate in this survey, please contact us by email at

If you wish to preview the questions, please contact us for a copy.
