Historical record of July 2026 wildfire smoke over Toronto. NASA captured the plume by satellite; check current AQHI and official guidance.<\/p>\n

NASA\u2019s July 14, 2026, NOAA-21 VIIRS image documented Ontario wildfire smoke moving southeast. By mid-July, nearly 850 fires were active in Canada, including more than 180 in Ontario.<\/p>\n

Historical satellite image from July 14, 2026. NASA Earth Observatory\/Lauren Dauphin, using NOAA-21 VIIRS data. It does not show current ground-level conditions in Toronto.<\/figcaption><\/figure>\n

NASA notes that smoke\u2019s effect on air quality depended on altitude: smoke high in the atmosphere had little ground-level impact, while conditions worsened where it moved closer to the surface. The image records the plume on that date; it cannot establish today\u2019s AQHI for any Toronto neighbourhood.<\/p>\n

The AQHI describes health risk for a local area and can vary with time and distance. Before outdoor activities, check Environment and Climate Change Canada\u2019s AQHI information and current readings<\/a>. Toronto Public Health also provides guidance for wildfire smoke and indoor air<\/a>. This article omits the July 2026 live readings that could not be reproduced from a preserved original official snapshot.<\/p>\n
