Forest fire smoke envelops Toronto, bringing poor air quality, pollution

Environment Canada has increased the air quality risk level for Toronto on Wednesday, up from Tuesday, as forest fire smoke continues to blanket the city.

A special air quality statement remained in place for the city on Wednesday night, saying high levels of pollution had developed due to the wildfires in Quebec and northeastern Ontario.

The federal weather agency predictsToronto will reach a risk level of nineon the Air Quality Health Index (AQHI) on Thursday. The index measures air quality based on how it will impact health. That number indicates high risk during the dayand means people may want to consider cancelling outdoor activities.

"There's a ridge over Ontario right now, so it means these winds are consistently bringing in poor air quality," said Trudy Kidd, an operational metrologist with Environment Canada.

On Tuesday, the city was at moderate risk and ona level five on thescale of one to ten.

Moderate risk levels meanthe general population need not cancel "usual activities" unless you start to experience symptoms like throat or cough irritation. For at-risk populations at that risk level, people are urged to consider rescheduling outdoor activities if symptoms are present, according to Environment Canada.

Those with lung disease, such asasthma, people with heart disease, older people, children, pregnant people and those who work outside are at higher risk of experiencing health effects, theagencysaid.

Don't light campfires, premier says

Premier Doug Fordcommented on the wildfires and poor conditions on Wednesday during question period, urging the public refrain from lighting campfires.

Ford said half of the forest fires in Ontario were started by lightning strikes and the other half were caused by human activity, such as campfires not being properly extinguished.

Environment Canada issued an air quality alert for Toronto on Wednesday as the city faced smoky, hazy conditions from wildfires in Quebec and parts of Ontario.

When the index indicates a high level of risk, the general population should consider rescheduling or reducing outdoor activities if symptoms are experienced. At-risk populations should reschedule outdoor activities, according to Environment Canada.

"Stop those outdoor activities and contact a health-care provider, if you or someone in your careexperiences shortness of breath or wheezing, asthma attacks, cough, dizziness or chest pains," Kidd said.

"Poor air quality will persist into the weekend," Environment Canada said. The agency's most recent statementwasfirmer than Tuesday, as the agency previously said there were hopes the conditions would ease bythe weekend. A low pressure system that could bring in cleaner air may arrive by Sunday, Kidd said.

"Wildfire smoke can be harmful to everyone's health even at low concentrations. Continue to take actions to protect your health and reduce exposure to smoke," Environment Canada said.

Air quality and visibility due to thewildfire smoke can fluctuate over short distances and can vary considerably from hour to hour. But wildfire smoke can be harmful even at low concentrations, it said.

Wear a mask if outside, Environment Canada suggests

If you must spend time outdoors, Environment Canada recommends wearinga well-fitted respirator type mask, such asan N95, to help reduce exposure to fine particles in smoke.

"These fine particles generally pose the greatest risk to health. However, respirators do not reduce exposure to the gases in wildfire smoke," the federal weather agency said.

Air quality risks are off the charts in Ottawa as smoke and haze cover large sections of central Canada. Toronto, Kingston, Ont., and Montreal are also feeling the effects as Environment Canada warns the air could be dangerous to human health for most of the week.

Environment Canada recommends the following:

• If you or someone in your care experiences shortness of breath, wheezing, severe cough, dizziness or chest pains, stop outdoor activities and contact your health care provider.
• If you are feeling unwell and experiencing symptoms, stay inside.
• Keep your indoor air clean.
• Keep your doors and windows closed if the temperature in your home is comfortable.
• Take a break from the smoke by temporarily relocating or finding a placein your community with clean, cool air such as a library, shopping mall or community centre.
• If you must spend time outdoors, a well-fitted respirator type mask that does not allow air to pass through small openings between themask and your facecan help reduce your exposure tofine particles in smoke.
• Be sure to check on people in your care and thosewho may be more susceptible to smoke.
• Evacuate if told to do so.
• Review your wildfire smoke plan and make sure you have enough medical supplies if the smoke continues to be an issue.

Toronto-area school board moves recess indoors

Due to the air quality warningfor the Toronto area, one schoolboardin the region hasopted to move recess inside for safety, while others say they are monitoring the situation.

TheYork Catholic District School Board said in a statement on Tuesday evening that indoor recess would be held indoors all day on Wednesday due to poor air quality.

The Peel District School Board said Tuesday that "strenuous outdoor activities"scheduled for Wednesday and Thursday would be cancelled, including athletic events. While outdoor recess is allowed to continue, it encouraged students to "avoid strenuous activity" and stay inside if they chose.

The Toronto District School Board made the same changes and issued the same guidance as Peel. Further, it said "TDSB schools will also ensure that HEPA air filters are continuing to be used," and it will monitor the situation. The Toronto Catholic District School Board left the choiceup to schools, stating that it recommends indoor recess be considered along with possibly rescheduling activities.

The Dufferin Catholic District School Board said it will also keep an eye on the air quality on Wednesday and that it would be going ahead with field trips due to difficulties in rescheduling.

Schools aren't the only thing in the city that'saffected in an e-mail sent to CBCNews, Toronto Blue Jays spokesperson MadeleineDavidsonsaid that due to poor air quality, the dome isclosed for Wednesday night's baseballgame.

On Wednesday night, the Toronto Zoo said it would limit its hours from 9:30 a.m. to 3 p.m. on Thursday due to poor air quality from the smoke and provide protective masks to staff and volunteers required to work outdoors.

The zoo said it would also limit access to the outdoors for some animals as well as limit the amount of time that staff and volunteers work outside.
