Air quality has seen significant improvements across most regions of Quebec and Ontario, according to Environment Canada. These enhancements are attributed to favorable changes in wind patterns and recent rainfall, which have collectively alleviated the problematic air quality issues that had been affecting areas east of the Prairie provinces, where wildfires continue to rage.
On Sunday, the federal department lifted air quality alerts for numerous regions in both provinces after experiencing two consecutive days of hazardous air quality warnings. Cities such as Toronto, Ottawa, and Montreal had been engulfed in a haze that contributed to concerns for residents' health and well-being. Despite the overall improvement, special air quality warnings or advisories are still in effect for certain locations, particularly communities situated east of Montreal, south of Quebec City, and in parts of northern Ontario, especially those in close proximity to the Manitoba border.
Meanwhile, the Prairie provinces continue to grapple with persistently poor air quality over the weekend. An extensive swath comprising six provinces and the Northwest Territories is currently facing degraded air quality and diminished visibility, largely due to ongoing forest fires. These fires have raised alarms across the region as the impacts are felt by residents who are advised to take precautions.
Looking ahead, Environment Canada has indicated that a low-pressure system is poised to move through the Prairies and into Manitoba and northwestern Ontario by Monday. This weather system is expected to deliver much-needed rain to regions struggling with uncontrollable wildfires, potentially providing some respite to the dire conditions being experienced.
In light of these circumstances, authorities are strongly recommending that individuals in the affected areas stay indoors whenever possible. They are also advised to avoid engaging in strenuous outdoor activities, particularly during times when air quality is at its poorest. These measures aim to protect public health and reduce the risk of complications arising from the poor air quality exacerbated by the surrounding wildfires.
