Fireworks Shows Across Canada Cancelled Due to Air Quality Concerns

Some Canada Day fireworks displays have been cancelled due to persistently poor air quality and concerns about exacerbating wildfires. Smoke from wildfires has affected large parts of the US and Canada, leading to cities like New York, Toronto, Montreal, and Washington DC having some of the world's worst air quality. The cancellation of fireworks displays in Montreal and the monitoring of the situation in Toronto reflect the ongoing concerns. The US Independence Day celebrations are also uncertain due to smoke drift, with areas in Minnesota, Wisconsin, and the northeastern US expected to be most affected. Extreme heat and drought have already led to fireworks cancellations in two Missouri towns. The Canadian wildfires are expected to continue affecting air quality until they are extinguished, and there have also been reports of wildfires in Texas and Arizona.
