Environment Canada and local Medical Health Officers expect an increase in health and safety risks from heat and are advising the public to take precautions. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to [email protected] or post reports on X using #BCStorm. Keep your house cool. Turn on your air conditioning (if possible), block the sun by closing curtains or blinds, or relocate to a cooler location such as a basement or public cooling centre. Fans alone cannot effectively lower core body temperature, especially for older adults. Use fans to pull in cooler air from outdoors, but if you or someone you care for is experiencing symptoms of heat illness, find a cooler space.

Air quality

Warnings

yellow warning - air quality - in effect (July 20, 2026) Metro Vancouver Regional District has issued a yellow air quality warning for the Eastern Fraser Valley due to elevated fine particulate matter (PM2.5). Where: Fraser Valley Eastern - Chilliwack, Agassiz, Hope Cause: Smoke from wildfires in British Columbia, including the Brunswick Complex near Boston Bar and wildfires in the southern Interior. Smoke levels can change quickly with weather and fire behaviour. What you can do: • Check in on others who may be more affected. People at higher risk include those with lung, heart or other chronic conditions, pregnant people, infants, children, older adults, and outdoor workers. • Improve indoor air quality. Use portable HEPA air cleaners or do-it-yourself box fan air cleaners. If your home has a built-in ventilation system, install filters rated MERV 13 or higher to remove smoke. If possible, adjust the ventilation system to reduce smoke coming indoors. • Keep windows and doors closed while running air filtration. If it’s hot, focus on staying cool. • Spend time in places with air conditioning if your home is smoky or too hot. Try community centres, libraries, or malls. • Seek medical help if you experience severe symptoms such as wheezing, chest pain, trouble breathing or severe cough. Call 911 in emergencies. • Manage chronic conditions and carry rescue medications with you (e.g. inhalers). • If you must be outside, a well-fitted N95, KN95, or KF94 mask offers the most protection. Medical masks offer some protection and single layer coverings (e.g. bandanas, scarfs, shirts) offer none. • Check the Air Quality Health Index (AQHI) often throughout the day because conditions can change quickly. See airmap.ca or gov.bc.ca/airqualitymap. • Sign up for air quality alerts at metrovancouver.org/aqalerts. ### Visit http://www.airhealth.ca for information on how to reduce your health risk and your personal contribution to pollution levels, as well as for current and forecast AQHI values. Please continue to monitor alerts and forecasts issued by Environment Canada.
