TORONTO 鈥� Environment Canada issued, then removed, what a meteorologist said was believed to be its first air quality statement in relation to holiday fireworks on Monday, prompting questions about why a major Hindu holiday was singled out.聽
A joint statement released by the federal agency and Ontario's Ministry of the Environment warned "high levels of air pollution" were anticipated across parts of Toronto and surrounding areas Monday night due to expected fireworks for Diwali combining with light winds and stagnating weather conditions.
By Monday afternoon, the weather agency updated its statement without mention of Diwali, but maintained its concerns about air quality.
An Environment and Climate Change Canada spokeswoman said in an email that the agency will often mention the source of air pollution in its air quality statements, but regrets the impact Monday's original statement had.
"The alert on October 24 was not meant to reflect negatively on those who are celebrating Diwali," Cecelia Parsons wrote.
"ECCC acknowledges that the alert should have been more culturally sensitive, and should not have referred to the specific event."
The president of a prominent Hindu umbrella organization representing several GTA temples said he was "disturbed" by the original statement, but glad to see the reference to Diwali dropped.
Hindu Federation president Pandit Roopnauth Sharma said he feared the statement would prompt backlash against the community.
"That is my concern, is for the safety of our community," he said. "I think it was purely wrong timing and not properly presented with facts to support any argument that there will be a negative impact.聽
"The person who made the statement didn't do their due diligence or consider the impact of their statement."
Temperatures Monday night were expected to be colder at ground level compared to the air above, setting up conditions for smoke from small fireworks to get trapped close to the ground, an Environment Canada meteorologist explained in an interview before the updated statement was released.
"Given the fact that a lot of these (fireworks) will be released near ground level, given the atmospheric conditions, that fireworks' smoke likely won't get mixed to a higher level in the atmosphere," said Geoff Coulson.
"It could stay at the ground level for a longer distance."
The special weather air quality statement forecasted moderate risks in Toronto, Brampton, Mississauga, Hamilton, and York and Durham regions from Monday evening into early Tuesday morning, with some potential short-term high risks to air quality.
Last year, under similar weather conditions, the agency recorded elevated air quality risks in the same areas during Diwali celebrations, Coulson said. When those same weather conditions started to materialize again, he said the agency decided to issue the special weather statement Monday morning.聽
"Last year, nothing was done because only after the fact were those measurements available, and they can actually see those values going up," he said. "Whereas this year, they're being a bit more proactive."
Diwali, also known as the Festival of Lights, is a major holiday celebrated by Hindus, as well as some Jains, Sikhs and Buddhists.
Several people, including Sharma, questioned the decision to issue a statement singling out Diwali fireworks, when fireworks are also common during Canada Day and Victoria Day celebrations.
Parsons said Environment and Climate Change Canada will ensure future messages aren't linked to specific cultural celebrations, and will instead only refer to air-pollutant sources such as wildfire or residential wood smoke, traffic or fireworks when they are known.
Coulson explained the atmospheric conditions forecasted Monday are less likely in late spring and summer, during the other holidays. He said Diwali celebrations also typically marked by more local celebrations with low-flying fireworks compared to higher-altitude Canada Day fireworks shows.
"What we find in other celebrations, like Canada Day, for example, there's not necessarily as many fireworks going off locally," Coulson said. "There were certainly large fireworks displays and in those ones the fireworks are launched high up into the atmosphere before exploding."聽
The special air quality statement itself, however, did not offer those explanations, which were only clarified in an interview with Environment Canada. The updated statement said weather conditions were expected to increase levels of fine particles and nitrogen dioxide, but provided no further reasons.聽
The statement says people sensitive to smoke, such as seniors or people with asthma, should take extra precautions to reduce exposure.
The statement's lack of clarity was troubling, said Sharma.聽
"I don't know what their objectives are. It certainly is not one that will do anything to inform people because there's so many questions to be answered," he said.聽
Mississauga and Brampton allow some fireworks on private property without a permit on Diwali, but Toronto requires one. In Brampton, those fireworks are only permitted to travel up to three metres, about the height of a basketball net. Mississauga's bylaw says only low-hazard recreational fireworks are allowed without a permit.聽
