Extreme heat wave expected to peak with record-breaking Monday
Monday is forecast to be the hottest day of an extreme, dangerous heat wave for the Ottawa-Gatineau area, with temperatures in the mid-30s and humidity making it feel like the mid-40s.
Heat warnings remain Monday and Tuesday for all of eastern Ontario and western Quebec.
The forecasted highs for some major local hubs are:
36 C in Ottawa and Gatineau, with humidity peaking at 44.
34 C in Maniwaki, with humidity peaking at 44.
34 C in Pembroke, with humidity peaking at 42.
33 C in Trenton, with humidity peaking at 44.
32 C in Kingston, with humidity peaking at 43.
Many of those temperatures would set daily heat records.
Ottawa topped out just under 30 C Sunday, with humidity making it feel like 37 at its hottest in late afternoon.
Health agencies say people are likely going to have to change their routines to stay safe in this dangerous heat.

CBC's Nkele Martin spoke with experts about dangerous symptoms to look out for and what types of activities are safe when the mercury starts to rise.
Health Canada recommends staying cool and staying hydrated when extreme heat hits.
That can mean everything from drinking lots of water and planning outdoor activities for cooler times, to preparing meals that don't require ovens and keeping nearby air-conditioned spaces in mind if needed.
This is true for yourself and for vulnerable people you know.
Watch for signs of heat exhaustion — like a headache, dizziness or a rapid heartbeat — and get to a cool place where you can drink water. Heat stroke, which includes confusion and very hot or red skin, is a medical emergency requiring a 911 call.
More resources may be available through your municipality. Ottawa, for example, has a map of public and other places to cool off.
New Ottawa fire ban
Some changes are also being made in the name of safety, such as the Western Québec School Board cancelling classes Monday.
Ottawa is now under an open air fire ban.

Weather and air quality warnings are active in parts of Canada: Here's what to know
Environment Canada has issued dozens of alerts warning of severe weather and air quality conditions across the country. Here's what to look out for, and where: Heat warnings in Ontario and Quebec Among the alerts active as of Thursday morning are more than 30 severe heat warnings in the Greater Toronto Area, Niagara Region and Greater Montreal. In the affected parts of Ontario, daytime highs are expected to reach up to 35 C, with humidex values peaking up to 44. Overnight, temperatures will fall, but are expected to remain near 21 C, 'providing little relief from the heat,' according to the department. Temperatures over 30 C and humidex values near 40 are also expected near Montreal, with 'uncomfortable' conditions over 20 C overnight. Environment Canada warns those in the area to 'take action to protect yourself and others,' including repeatedly checking on older adults, those living alone and those at risk of heat-related illness. Early signs of heat exhaustion include headache, nausea, dizziness, thirst, dark urine and intense fatigue, the department notes. Those experiencing heat exhaustion should stop any activity and drink water to rehydrate. Symptoms including red and hot skin, a change in consciousness, as well as those mentioned above, may be signs of heat stroke. In the event heat stroke occurs, seek emergency medical attention for those affected, and in the meantime, help them cool down by moving them out of hotter areas, removing extra clothing and applying ice packs or cold water to their body. Generally, those in the area should be sure to stay hydrated and make use of shades and blinds, air conditioning, fans and cooler areas of their living space, where available. Outside of the home, public spaces such as cooling centres, libraries, community centres and shaded parks may provide relief from the heat. Limit direct exposure to the sun, avoid outdoor activity during the hottest parts of the day and wear light, loose-fitting clothing and a hat to stay cool. Environment Canada warns that you should never leave pets or people, especially children, in a hot car. Quebec, B.C. storm warnings Parts of Quebec near the Ontario boundary are under severe storm watches as of Thursday, from the Ottawa River Valley north toward Val-d'Or. 'Conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts, large hail and heavy rain,' the alert reads. 'Some of these thunderstorms could produce a tornado.' Residents are warned that 'nautical activities may be hazardous,' due to sudden gusting winds. Large hail, flash floods and lightning are also possible, increasing risks of injury or death. 'When thunder roars, go indoors!' the department writes. Further north, in the Joutel and Matagami area, a rainfall warning is in effect with up to 50 millimetres of precipitation possible. A separate rainfall warning is active in northern British Columbia, north of Fort St. John, with between 50 and 70 millimetres of rain expected. Air quality in the Prairies A large region along the Manitoba-Saskatchewan boundary is currently under air quality warnings due to wildfire smoke. The affected area stretches from Leaf Rapids and Snow Lake in northern Manitoba out west to Beauval, Sask. 'During heavy smoke conditions, everyone's health is at risk regardless of their age or health status,' the warning reads. Residents are advised to limit time spent outdoors and keep windows and doors closed. If heat is also an issue, however, keeping cool should be the priority. Products including respirator masks and air filters are recommended. Those affected by wildfire smoke should seek medical attention if symptoms, including eye, nose and throat irritation, headaches, cough, wheezing or chest pains, progress to the point of a medical emergency.

Leaf Rapids crews battling wildfire after 'very serious turn' forced essential workers to leave, province says
Social Sharing Leaf Rapids fire crews had to temporarily retreat from the frontlines of wildfire fighting Wednesday as one of several fires threatened the northern Manitoba community. In a statement posted to Facebook at 8:15 p.m. on Wednesday, the town's administration said the wildfire burning northwest of the town jumped the Churchill River and began spreading through the community's industrial area. The community Facebook page suggested all personnel, including firefighters, were evacuating the community due to wildfire spread and thick smoke. The post said firefighters may not be returning to the community for some time. A provincial spokesperson told CBC News Thursday morning that municipal fire crews did not, in fact, evacuate. Instead, they retreated to previously established "safe zones" for a time, before returning and resuming their work. "While there was a very serious turn in the fire situation last night it is important to note that crews from the Office of the Fire Commissioner and the Manitoba Fire service (local and municipal firefighters) did not evacuate the town last night," the provincial spokesperson said in a statement Thursday. "Essential workers did leave, but the emergency crews dedicated to protecting the community did not leave and remained at the community while the fire passed through." The province's wildfire map showed that fire was more than 2,500 hectares in size as of Tuesday. It is the smallest of the three major wildfires surrounding the community. Another fire southwest of the community has grown to more than 30,300 hectares, while a wildfire to the east has burned 15,500 hectares as of Tuesday, the province's data showed. All three wildfires are out of control. Leaf Rapids, located about 155 kilometres northwest of Thompson, declared a state of emergency on July 7. The town told its 300 residents they had to leave within 24 hours. Ervin Bighetty has been staying in a Winnipeg hotel alongside his family since they were evacuated two weeks ago. The former mayor told CBC News he was sad to see that firefighters would start leaving the community on Wednesday night. He said returning to Leaf Rapids doesn't seem realistic right now. "I don't know when we're going to go home, if we're going to have a home to go to," Bighetty said. "But what matters to me is that my family is safe. I know where they are, I can go down the hallway and go see them," he said. The Manitoba government spokesperson said some vacant structures have been lost to fires, though only one occupied residence has been damaged as of Thursday morning. The province is expected to provide an update on the status of the firefight in Leaf Rapids on Thursday.
