Here comes the hot weather… again
Environment Canada is warning of another multi-day heat event starting on Saturday.
They say daytime temperatures will reach 30 to 33 degrees Celsius, but with the humidex, it will feel closer to 35 or even 40.
Overnight, temperatures are only expected to drop to between 19 and 23 degrees Celsius.
All of southern Ontario and much of the northern part of the province are included in the alert.
Environment Canada said 'slightly' cooler temperatures are not expected until the middle of next week.
Signs of heat illness
Heat illness is a serious concern when the mercury rises, especially in older adults, infants, young children, pregnant people, those with physical or mental illnesses, people with mobility issues, those who work outside and the homeless community.
Symptoms of heat exhaustion include:
Headache
Nausea or vomiting
Dizziness or fainting
Extreme thirst
Dark urine and decreased urination
Intense fatigue
Confusion or lack of coordination
Skin rash
Muscle cramps
Heavy sweating
Rapid breathing and heartbeat
Heat stroke, meanwhile, is considered a medical emergency.
Those symptoms include:
High body temperature
Very hot, red skin
Confusion or change in consciousness
Dizziness or fainting
If someone is experiencing heat stroke, experts advise moving them to a cool place, giving them water and placing ice packs on their body. Call 911 immediately.
Beating the heat
The key to avoiding heat illness is to plan ahead.
Here are a few things to keep in mind:
Know the weather forecast before going outside
Modify your plans according to the weather
Drink plenty of cool liquids, especially water, even before you feel thirsty
Avoid drinks that are high in sugar, caffeine or alcohol
Wear loose-fitting, light-coloured clothing made of breathable fabric
Seek shade
Avoid sun exposure if you can
Take breaks as needed
Avoid using your oven
Take a cool shower or bath
Take a break by spending a few hours in a cool place
Close blinds and shades,
Turn on air conditioning or use a fan
Cooling centres
The best way to get relief from the heat and humidity is to seek out a designated cooling centre.
The Region of Waterloo has locations listed on their website. They include libraries, community centres, museums and regional offices, as well as public swimming pools and splash pads.
Guelph also has a list air-conditioned libraries and facilities open to the public, including the locations of splash pads and swimming pools in the community.
A list of cooling centres, pools and splashpads in Brantford can be found here.
Protecting your pets
Leaving pets inside a hot vehicle, even for a few minutes, could be dangerous.
Dogs can experience heatstroke, which could lead to organ failure and, ultimately, death.
Signs of an overheated pet include:
Excessive panting
Drooling
Vomiting
Collapsing
Lethargy
Tongue can appear red or hang out of their mouth
If your pet is suffering from the heat, it's a good idea to gradually cool them down.
Experts suggest using a cool blanket or towel that is wet. Avoid using ice.
Owners should keep pets at home when the temperature climbs but if they need to go outside, keep them off the pavement as much as possible, only go for a short walk, or take them out in the morning or evening when it's cooler.

Heat wave in parts of Ontario, Quebec expected to last until Monday: meteorologist
Social Sharing Hot, humid weather settled over much of Ontario and parts of Quebec on Saturday with Environment Canada warning of a multi-day heat wave set to bring even higher temperatures Sunday and Monday. Environment Canada said several days of sweltering conditions began taking hold of southern Ontario and half of northeast Ontario on Saturday, blanketing communities including Windsor, Timmins, Sudbury, Toronto and Ottawa. A severe weather meteorologist with the federal agency said the wave extended across the provincial border with Quebec to encompass regions including Montreal, pushing daytime highs to 35 C in southern areas and 33 C in the north, with the humidex at or near 40 C. Weiqing Zhang warned that Saturday was just the beginning of uncomfortably warm weather. "The hottest day will be tomorrow — Sunday — and then Monday," Zhang said. Some relief may come Monday for northern areas, Zhang added, but southern regions stretching from the Ottawa area all the way to Windsor could see high temperatures lasting into Tuesday. GTA under 6th heat warning this year Parts of Newfoundland and Labrador also received heat warnings Saturday, with near 30-degree temperatures expected in areas including St. John's and Gander. Zhang said the criteria for heat warnings in the Atlantic province is slightly lower than those for Ontario and Quebec. Zhang said the Greater Toronto Area has had a particularly hot year, noting the current heat warning marked the region's sixth for 2025. That's compared to four warnings issued in 2024, a benchmark she said the GTA reached this past July. WATCH | Some Torontonians have struggled to stay cool during earlier heat waves this summer: 'Unliveable conditions': Why it's impossible to stay cool for these Toronto residents 2 months ago As the GTA's heat wave rages on, some residents have been struggling to stay cool. CBC's Dale Manucdoc speaks to Torontonians living in buildings without air conditioning and those who have no choice but to work outside. She expected another heat warning could be issued later in August. "I can't guarantee it but based on the current guidance it looks like at least in late August we'll probably have another one — the week of Aug. 20," said Zhang. "This year the whole, the big weather pattern is favourable for hot and humid conditions." The current heat bout will offer slightly cooler nights but it will still be warm, she added, with overnight temperatures expected to linger in the 20s. Zhang advised people to limit direct exposure to the sun and heat, if possible, with any outdoor activities scheduled during the coolest parts of the day. The weather agency warned the heat wave could pose health risks and says to watch for signs of heat exhaustion, including headache, nausea and dizziness.

Premier to provide update on New Brunswick's wildfire situation
The New Brunswick government will give an update on the provincial wildfire situation at 2:30 p.m. AT Saturday. Premier Susan Holt, Minister of Natural Resources John Herron and Minister of Justice Rob McKee, on behalf of Public Safety, will take part. Roger Collet, a wildfire prevention officer, will also be answering questions. CBC will broadcast the livestream. As of Friday midnight, the DNR put a ban on forestry operations such as harvesting, forwarding, skidding, scarification, chipping and all pre-commercial thinning and cleaning on all forested Crown and private lands across the province. The ban on forestry operations will be in effect until midnight Aug. 12, the release said. Trucking, road construction and maintenance, vegetation management and tree planting are still allowed to continue, said the department. The entire province including provincial parks remain under a burn ban. A wildfire which broke out earlier in the week on Oldfield Road, about 16 kilometres north of Miramichi, has grown to approximately 160 hectares, New Brunswick's Department of Natural Resources spokesperson Nick Brown said in an email on Saturday morning. "Over the next several days, the province is expected to remain under extreme fire weather conditions, with high winds, high temperature, and low humidity. "It is a very dangerous situation with the state of fuels [ignitable materials in the forests]," said Brown. Two water bomber airplanes from Quebec are assisting with the ongoing extinguishing operation, he said. Fires that started on Friday in St. Paul and near Harvey are under control," Brown said. Highway 8 near Miramichi between Route 450 and Oldfield Road is currently closed, according to the New Brunswick Emergency Measures Organization. Russellville Road and McHardy Road are also closed with diversions in place.
