A new study released by Statistics Canada on Wednesday has revealed a significant correlation between extreme heat events and increased mortality rates in Canada’s largest cities over the past two decades.
The research analyzed data from the Canadian Vital Statistics Database and Environment and Climate Change Canada, focusing on the period from 2000 to 2020. Findings indicate that extreme heat events were associated with approximately 670 excess non-accidental deaths and 230 excess deaths due to cardiovascular and respiratory causes.
Notably, individuals aged 65 and older were predominantly affected, highlighting the vulnerability of older populations to extreme temperatures. The study suggests that higher mortality risks during extreme heat events occurred in cities with larger proportions of rental households and in areas less accustomed to such events. Residents in these regions may have limited access to resources that aid in adapting to heat or may be less acclimatized to sudden temperature increases.
Extreme heat events were defined by Environment and Climate Change Canada as periods of two or more consecutive days with unusually high temperatures. As global climate patterns continue to shift, the frequency and intensity of these events are a growing concern.
The implications of this study underscore the need for proactive measures to protect vulnerable populations, especially older adults, from the health risks associated with extreme heat. Public health initiatives and urban planning strategies that address heat adaptation could be vital in mitigating future risks.
