Residents across much of the Greater Toronto and Hamilton Area, Halton, Durham and Niagara regions are being advised to take precautions as a long-duration heat event continues through today.<\/p>\n
Environment Canada says daytime high temperatures are expected to reach around 30 C, while overnight lows will remain near 20 C, offering little relief from the heat.<\/p>\n
The warning affects communities including Toronto, Mississauga, Brampton, Oakville, Milton, Burlington, Oshawa, Whitby, Pickering, Clarington, Hamilton and municipalities throughout Niagara Region.<\/p>\n
In addition to the heat, officials say the hot and humid conditions could lead to worsening air quality. The Air Quality Health Index (AQHI) may approach the high-risk category, particularly for seniors, young children, pregnant people and those with heart or respiratory conditions.<\/p>\n
Health officials recommend residents:<\/p>\n
Drink plenty of water, even before feeling thirsty
\nLimit strenuous outdoor activities during the hottest parts of the day
\nSeek air-conditioned spaces when possible
\nCheck on older adults, neighbours and vulnerable family members
\nWatch for signs of heat-related illness, including dizziness, nausea, headache and extreme fatigue<\/p>\n
Temperatures are expected to remain elevated throughout the day, with humid conditions making it feel even warmer in many areas.<\/p>\n
Residents are encouraged to monitor local forecasts and air quality reports and take appropriate precautions until cooler conditions return.<\/p>\n
