8:10 a.m. - Family doctor sees more patients with breathing difficulties due to smoke

Dr. Ashley Sebastian is a family physician from Brampton and said Wednesday that she has seen an increase in the number of patients coming in with breathing difficulties.

Sebastian warned that the deteriorating air quality is especially dangerous to vulnerable members of the population, including the elderly, young children, pregnant people, and the unhoused.

“So, we need to pay very close attention to this, and if you do need help, seek help at your local emergency department, if you can, or visit your family doctor.”

She said people who must be outside, especially those with respiratory issues or other health concerns, should consider wearing a mask to help filter out particulate matter.

“(Masks) can reduce and filter some of the particulate matter that might lead to some breathing difficulties. So certainly, you can wear masks to help improve your breathing quality,” Sebastian said.

He noted that smoke has reached the U.S., including over his home state of Michigan.

“I commend the outstanding cooperation between the United States and Canada as we confront these fires together. Our two governments are monitoring and sharing information in real time – coordination that reflects our partnership at its best," Hoekstra said in a statement.

6:10 a.m. - Ford posts video on Ontario’s wildfires

In a video posted on social media Wednesday, Ontario Premier Doug Ford addressed the ongoing wildfires in the province, pointing out that his government has 156 fire crews and nearly 150 water bombers and helicopters working to extinguish them.

“Our government will not spare a penny to keep people safe,” Ford said, proceeding to tout his government’s investment in forest firefighting, such as adding new personnel and adding new water bombers and helicopters.

He also acknowledged the help the province is getting from Alberta and Yukon. The premier also recognized those who are helping displaced residents.

“I’m encouraged by the compassion and the care we’ve seen from people across the province who are opening their communities to their fellow Ontarians who have been forced to evacuate as a result of these fires,” the premier said.

“I promise that our government will continue to do everything we can to protect people and communities across Ontario.”

The Ontario Liberal Party criticized the Ford government on Wednesday for underspending on emergency forest firefighting. The party said Ontario budgeted only $150 million this year, down from $271 million last year.

“A realistic base budget would allow the ministry to recruit and retain crews, maintain aircraft, secure equipment, and prepare evacuations before communities are threatened, rather than scrambling once fires are burning and families are being forced from their homes,” Ted Hsu, the Ontario Liberal critic for Rural Affairs, Natural Resources, Mining & Forestry, said in a statement.

“The North will come together, as it always does, but its resilience cannot excuse a government that failed to prepare. Protecting Ontario means protecting all of Ontario, with enough crews, equipment and funding in place before the next emergency.”
