EPA issues air quality warnings due to Canada fires
In the U.S., smoke from Canadian wildfires was detected drifting through Montana, North Dakota and northern Minnesota.
Smoke from Canadian wildfires is impacting multiple U.S. states, even as far south as Florida.
As over 203 active fires rage in Canada as of June 4, according to the Canadian Interagency Forest Fire Center, wind carrying smoke from the fires have engulfed states in the eastern and central U.S.
Many states are reporting moderate air quality levels, but conditions are worse in areas closer to the U.S.-Canadian border.
Multiple states in the mid-to-upper Midwest have been flagged as unhealthy for sensitive groups and unhealthy for the overall population, regardless of health conditions, according to the U.S. Environmental Protection Agency's AirNow tracker. Areas of Wisconsin and northern Michigan are reporting "unhealthy" air quality levels.

Side effects of inhaling wildfire smoke
Wildfire smoke can irritate one's eyes, nose, and throat and cause:
Coughing
Chest tightness
Shortness of breath
Dizziness
Fatigue
Particulate matter, a type of air pollutant that is made of small particles of solids or liquids that are suspended in the air, is one of the main components of wildfire smoke, as USA TODAY previously reported.
According to Yale Medicine, the particles can be 10 micrometers, PM 10, or as small as 2.5 micrometers, PM 2.5, and the smaller one poses a lot of health risks.
PM2.5 is so tiny it can easily pass people's usual defense mechanisms and dive deep into their lungs. Not only can it damage lung function, but it can also pass into the bloodstream and travel to other organs.
The following is linked to exposure to the PM 2.5:
Heart attack
Stroke
Lung cancer
Decline in cognitive function

Niagara Falls MPP backs cross-party push to extend OHIP for prostate cancer testing
Momentum continues to grow for Wayne Gates' push to extend OHIP coverage for prostate cancer screening. On Thursday, the New Democrat supported independent MPP Bobbi Ann Brady's motion to extend Ontario Health Insurance Plan coverage for PSA testing — a cause Gates has championed at Queen's Park for the past six years. 'This isn't about politics — it's about saving lives,' said Gates. 'Every year, thousands of men are diagnosed too late because cost is a barrier to early testing. We can fix that. I'm proud to support MPP Brady's motion and I hope every member in the legislature does the same.' Brady, the province's lone independent MPP, representing nearby Haldimand-Norfolk, said she has previously stood and called on the government to support Gates' effort. 'Seeing no movement on this initiative and inspired by the longtime calls for this important change from my colleague Wayne Gates … I have renewed the call with the motion asking the Ford government to cover the cost of PSA tests through OHIP when referred by a health-care provider.' Independent MPP Bobbi Ann Brady. The call to action comes just ahead of Father's Day — a time Gates said is 'perfect' for raising awareness of men's health. He said prostate cancer is the most commonly diagnosed cancer among Canadian men. PSA testing now is not covered by OHIP unless there are symptoms evident, often making it too late for early intervention, said Gates. The motion wants OHIP to cover the cost of tests for patients referred by a health-care provider, saving them the roughly $40 charged by private labs in Ontario. Although earlier readings of Gates' bill won all-party support, the government defeated the bill last year. Canadian Cancer Society's Dr. Stuart Edmonds. A cancer diagnosis costs Canadians an average of $33,000 in their lifetime — on top of that, there are other out-of-pocket expenses like PSA testing, said Dr. Stuart Edmonds, executive vice-president of mission research and advocacy at the Canadian Cancer Society. He said prostate cancer strikes one in eight Canadian men. 'We believe that early detection of prostate cancer shouldn't come with a price tag. The question shouldn't be, 'Can you afford the test?' It should be, 'Do you need it?'' Gates said the latest motion will be debated at a later date, adding it's significant to have Brady — a woman — at the forefront of the effort. 'I think it's really important because it affects the entire family — it may be men that get prostate cancer, but it affects their spouses, the kids. It's good news for us as we try to put more pressure on the government to do this.' He said there's also growing support from firefighter groups across Ontario. 'Firefighters are more likely to get prostate cancer than the general public by 1.41 per cent, so this is now one that the provincial association and the local firefighters are now raising the awareness of trying to get it covered.' Gates said continued awareness is also important. 'Early detection is the key. We think it's a very important motion. I'm glad that it's supported by the Liberals. I'm glad that it's supported by the Greens. I'm glad it's supported by Bobbi Ann. Let's make this the year we get it done — together.' Error! Sorry, there was an error processing your request.

Marc Garneau died after 'short but very difficult battle' with cancer, former staffer says
Marc Garneau died this week after being diagnosed with two types of cancer earlier this year, his former staffer says. The first Canadian to travel to space and former cabinet minister died on Wednesday. He was 76. Marc Roy, Garneau's former chief of staff, told CBC's Power & Politicsthat the former minister had been diagnosed with lymphoma and leukemia earlier this year. "He fought a short but very difficult battle with two very rare types of cancer," Roy told host David Cochrane. "Although his diagnosis was only a couple of months ago, he was well until four or five weeks ago. So it went very, very quickly … it's a very, very tough loss." Roy said Garneau only shared his diagnosis with a small circle that agreed to respect his wish for privacy. "[It was] something he wanted to keep with his family so he could concentrate on his time with his family and not distract his family by the attention it could have gotten," Roy said. WATCH | It's a tragic loss,' says former chief of staff: Beyond his legacy as an astronaut, Garneau held a number of federal cabinet positions since 2015, including in transport and foreign affairs. Roy said Garneau was "tremendous" to work for as he reflected on his time in politics. "It's a huge loss to government. I think that his years in Ottawa are filled with many contributions to improving safety and expanding policy. I think he will be remembered for that for decades to come," Roy said. The House of Commons held another moment of silence for Garneau on Thursday and MPs took time to pay tribute to their former colleague. "He reminded us that Canadians can dream big, that we could aim for the stars quite literally," Government House leader Steve MacKinnon said. "He became a powerful symbol of the achievement and the accomplishment of this great country of ours." Like MacKinnon, other MPs reflected on how Garneau inspired Canadians. "Mr. Garneau, the future will always be inspired by your life, which was so inspiring for all Canadians," Conservative MP Gérard Deltell said in French. WATCH | Garneau's 'extraordinary ride': Bloc Québécois MP Rhéal Fortin said Garneau paved the way for other Canadians to journey to space, including Chris Hadfield and Julie Payette. "He showed us the way to the stars," Fortin said in French. Fighting back tears, Green Party Leader Elizabeth May said it was hard to say goodbye to "someone who was unfailingly kind [and] unfailingly respectful." "We've lost a very great human being, and to his entire family: my deepest condolences and sympathy — and know that in that space where he looks down at planet Earth now, I think it's a place called heaven."

Doctor warns of respiratory risks from wildfire smoke
GRAND RAPIDS, Mich. (WOOD) — Air quality reached unhealthy levels across the state Thursday as smoke from the Canadian wildfires drifted south. Michigan declared an air quality advisory lasting through noon Friday. Dr. Julia Becker, a physician in the Pulmonary and Critical Care Division at Corewell Health, takes care of patients with significant lung disease like and . Since wildfire smoke drifted south, she said her patients have seen much worse symptoms. But it's not just them. Canada wildfire smoke leaves West Michigan in a haze 'Even healthy people I think might notice some coughing, headaches, sore throat,' she said. 'All those conditions are gonna feel worse when the air quality's this bad.' Becker said that healthy individuals can experience those symptoms when the air quality is in the unhealthy range, like it was in West Michigan Thursday. Certain people are especially at risk, she said. That can include people over the age of 65, under the age of 18, those who are pregnant, those who have heart or lung disease and those who often work outdoors. Becker said you can notice the effects in minutes and the damage can be long-term. 'People have increased events with their heart and lungs up to three months after the event,' she said. 'People have more heart attacks, more heart rhythm problems, more . The effects of all this inflammatory bad stuff we breathe in last for months. Clean air is actually extremely important.' She recommended staying indoors if you can, keeping your windows shut and having a good air filter, preferably a HEPA filter. In Grand Rapids and Kalamazoo, you can check exactly what the air quality is like in your neighborhood using . Air quality sensors are posted on poles at about a dozen spots in Grand Rapids, including at Sixth Street Bridge Park and on the Medical Mile. Air quality worsens in eastern US as Canadian wildfire smoke hangs over Midwest Darren Riley started the nonprofit in 2021 to help show that in a community, air quality is not created equal. 'For one side of the block, it may be a poor air quality day for that community,' he said. 'Other side of the city could be a clean air day. You may have communities that are neighboring heavy trucker routes, heavy highways. You have things we do ourselves like wood fire smoke and idle our cars when we're picking up our kids.' The website has a map where you can check air quality by location and get alerts when the air is bad. JustAir is active in nine other states too. 'It's very important we investigate how we can mitigate those disparities between neighborhood and neighborhood,' he said. 'The only way to do that is to have data to do better.'
