Take action to protect yourself and others – extreme heat can affect everyone’s health. Determine if you or others around you are at greater risk of heat illness. Check on older adults, those living alone and other at-risk people in-person or on the phone multiple times a day.
Watch for the early signs of heat exhaustion in yourself and others. Signs may include headache, nausea, dizziness, thirst, dark urine and intense fatigue. Stop your activity and drink water.
Heat stroke is a medical emergency! Call 9-1-1 or your emergency health provider if you, or someone around you, is showing signs of heat stroke which can include red and hot skin, dizziness, nausea, confusion and change in consciousness. While you wait for medical attention, try to cool the person by moving them to a cool place, removing extra clothing, applying cold water or ice packs around the body.
Drink water often and before you feel thirsty to replace fluids.
Close blinds, or shades and open windows if outside is cooler than inside.
Turn on air conditioning, use a fan, or move to a cooler area of your living space. If your living space is hot, move to a cool public space such as a cooling centre, community centre, library or shaded park.
Follow the advice of your region’s public health authority.
Plan and schedule outdoor activities during the coolest parts of the day.
Limit direct exposure to the sun and heat. Wear lightweight, light-coloured, loose-fitting clothing and a wide-brimmed hat.
Never leave people, especially children, or pets inside a parked vehicle. Check the vehicle before locking to make sure no one is left behind.
A prolonged period of hot and humidity continues.
What:
Daytime highs of 31 to 34 degrees Celsius and a humidex of 37 to 42.
Overnight lows of 19 to 21 degrees Celsius, providing little relief from the heat.
When:
Continuing through Thursday.
Additional information:
Showers and thunderstorms moving through Thursday morning are expected to keep daytime temperatures relatively cooler for most regions, bringing an end to the heat event. For regions not affected by showers, a cooler airmass will bring an end to the event by Thursday night.

HAMILTON, Ontario, July 16, 2025 (GLOBE NEWSWIRE) — The United Steelworkers union (USW) says today’s announcement from Prime Minister Mark Carney reflects major wins for workers – delivering on demands the union has made not only during the current crisis, but over the past decade.
The union welcomes the move to expand and tighten tariff rate quotas (TRQs) on non-FTA countries to 50% of 2024 levels and on FTA at 100% of 2024 volumes, with a 50% tariff on excess imports. The USW also applauds the governments trailblazing measures to address global overcapacity directly as the USW has called for and the government’s commitment to require Canadian steel in federally funded infrastructure projects – something the union has demanded for years. The USW is also encouraged by the government’s $1billion commitment through the Strategic Innovation Fund to address domestic steel capacity gaps and build domestic supply resiliency. This is an issue the USW has been bringing attention to for years.
“These are significant wins for our members. We’ve been calling for expanded and tighter import limits since the June announcement and for Buy Canadian rules for years and it’s encouraging to see those demands finally reflected in federal policy,†said Marty Warren, USW National Director. “Mandating Canadian steel in public projects isn’t just good for jobs – it’s good for the environment and for supply chain resilience.â€

While today’s plan delivers long-term investments and structural changes the union has long demanded, USW stresses the need for continued vigilance. The union expects to be closely consulted on implementation and calls for ongoing monitoring to ensure the new measures are effective in preventing further harm to Canada’s steel sector.
The USW also recognizes the government’s recent expansions to Employment Insurance but continues to call for further improvements with better access and increased income support for affected workers.

The USW says it will continue to work with the federal government to monitor and review the effectiveness of the TRQ program and the import situation and on building a long-term industrial strategy, but it still needs to deliver urgent and immediate protections for workers.
“Steelworkers have fought for these changes for years – today’s announcement is a direct result of that pressure,†said Warren.

The USW represents 225,000 members in nearly every economic sector across Canada and is the largest private-sector union in North America, with 850,000 members in Canada, the United States and the Caribbean.
Each year, thousands of workers choose to join the USW because of the union’s strong track record in creating healthier, safer and more respectful workplaces and negotiating better working conditions and fairer compensation – including good wages, benefits and pensions.
