Canada is entering unchartered territory as it regularly experiences record high temperatures negatively affecting the health and well-being of heat-vulnerable men and women. Recently, we showed that increasing age is associated with an impaired physiological capacity to dissipate heat and blunted cardiovascular adjustments to heat stress. Consequently, older adults are at increased risk of heat-induced illnesses or death. Age-associated chronic diseases such as type 2 diabetes or hypertension can worsen this response. Given that periods of extreme heat will likely be more frequent, intense, and deadly within the next few decades and Canada’s population is aging rapidly, the development of evidence-based heat protection action to mitigate adverse health impacts of heat in heat-vulnerable Canadians is crucial.
In order to better understand the impact of heat stress and heat strain on heat-vulnerable Canadians, we must understand the conditions and causes that lead to elevated levels of heat strain that can compromise health and well-being. By acquiring this knowledge we can develop and disseminate consensus-based, equitable heat mitigation strategies including messaging to protect the health of heat-vulnerable men and women.

To facilitate this process, we ask that individuals 50 - 85 years complete the questionnaire below. Your participation consists of completing one questionnaire of 90 questions which will take approximately 20 minutes. We ask that you only complete the questionnaire once. All questions with an asterisk (*) must be answered to proceed to complete and submit the questionnaire.

Your responses are entirely confidential and anonymous. In order to minimize the risk of security breaches and to help ensure your confidentiality, it is recommended that you use standard safety measures, such as signing out of your account, closing your browser, and locking your device when you are no longer using it/when you have completed the survey.

All raw data collected from the online survey will be stored using alphanumeric coding systems. Data will be kept in the Human and Environmental Physiology Research Unit in locked file cabinets, and only Dr. Kenny ( will have access to your data. You can request to discuss the results of the questionnaire at the completion of the study.  The data collected in this study will be published in scientific journals. The data will be destroyed (deleted from computer storage) immediately following the publication of the data.  

It is important to note that you are under no obligation to participate. If you choose to participate, you can withdraw from the survey at any time.  However, please note that given the survey is anonymous, once the survey is completed, you will be unable to withdraw your data from the study as we will be unable to retrace your individual dataset. 

By completing and returning the survey, I understand that I may contact the lead researcher Dr. Glen Kenny ( or the student-research lead Ms. Emily Tetzlaff ( If I have any questions, I may contact the I may contact the Office of Research Ethics and Integrity via email ( or telephone (613-562-5387).
