Ontario is consistently setting new records for extreme heat, indicating that the hot and humid summer months will become increasingly uncomfortable and hazardous. In early June, the province experienced a heat wave of unprecedented magnitude, accompanied by smoky and hazy conditions caused by nearby wildfires. Environment Canada issued high air quality risk levels for major cities like Toronto and Ottawa.

The consequences of extreme heat in Ontario are numerous and far-reaching.
They include:

Health risks: The population is vulnerable to heat-related illnesses such as heat stroke and heat exhaustion.

Increased mortality rates: Extreme heat events can lead to a rise in deaths, particularly among the elderly and those with pre-existing health conditions.

Reduced air quality: Heat waves worsen air pollution, compromising the overall air quality and exacerbating respiratory problems.

Negative impacts on agriculture: Heat waves can harm crops, livestock, and overall agricultural productivity.

Overloading of power grids: High demand for cooling and air conditioning can strain the power supply, leading to potential blackouts or brownouts.

Strain on infrastructure: The extreme heat can cause damage to roads, bridges, and other infrastructure, necessitating repairs and impacting transportation systems.

As the world grapples with the ongoing climate change crisis, there is growing awareness of the dangers associated with extreme weather events like heat waves. It is crucial to have essential information and facts about heat waves to mitigate their adverse effects, particularly for those at higher risk, such as the elderly and individuals with specific health conditions.
