Avertissement sérieux : préparer les régions du Canada à la chaleur extrême

The document highlights the growing threat of extreme heat in Canada, noting its severe health impacts and economic costs. It advocates for a combination of mechanical cooling, urban greening, updated labor standards, and improved early warning systems to mitigate these risks.

• Extreme heat poses severe health risks, particularly for vulnerable groups such as the elderly, low-income individuals, and those with chronic illnesses or mental health issues. A six-day heatwave in British Columbia in 2021 resulted in 619 deaths, with 93% of the deceased lacking functional home air conditioning.
• Mechanical cooling and urban greening initiatives, such as green roofs and tree planting, are effective adaptation strategies. In the continental lowlands of British Columbia, combining these two measures could lower heat-related hospitalization costs by 30% by the middle of the century.
• Current heat warnings from Environment and Climate Change Canada are issued only one or two days in advance, which is less proactive than systems in the United States, Europe, and Australia that provide warnings several days earlier.
• Implementing professional temperature standards and flexible work schedules can protect workers and reduce economic losses. For instance, shifting harvest times to after midnight during a British Columbia heatwave could prevent annual GDP losses of 4 million dollars by the 2030s.
