TORONTO, July 2, 2026 – Peel Public Health issued a heat warning on June 30, with hot and humid conditions expected to continue until at least July 3 and possibly into the weekend. Seniors living alone, people with chronic health conditions, tenants without air conditioning and outdoor workers may experience dizziness, nausea, a rapid heartbeat or confusion if they remain in high temperatures for extended periods.
Peel Region issues a heat warning when daytime temperatures are expected to reach 31 C or higher, overnight temperatures remain at 20 C or higher, or the humidex reaches 40. Persistently high overnight temperatures can prevent homes from cooling naturally. Top-floor apartments, poorly ventilated rental units and homes without central air conditioning may remain very hot even after sunset.
Public health officials advise residents to drink water regularly rather than waiting until they feel thirsty and to reduce outdoor activity from midday through the afternoon whenever possible. Anyone experiencing headaches, muscle cramps, nausea, reduced urination, rapid breathing or a fast heartbeat should move to a cooler place and rest as soon as possible. If someone becomes confused, loses coordination or faints, call 911 immediately.
Residents without air conditioning can visit libraries, community centres, swimming pools, splash pads or other open public facilities to cool down. Locations and operating hours differ across Brampton, Mississauga and Caledon, and some facilities may change schedules because of maintenance, events or capacity limits. Residents should check their municipality’s website or call before leaving.
Families with seniors living alone should actively check the indoor temperature, water intake and physical condition of their relatives. Using only an electric fan may not provide enough cooling during extreme heat, especially when the indoor air is already very hot. Seniors who need to visit a public facility should arrange transportation in advance rather than waiting until they feel unwell.
Delivery workers, construction workers and landscapers who spend long periods outdoors should identify rest areas and hydration arrangements before starting work. Anyone experiencing significant dizziness, weakness or nausea should not continue working or drive on their own.
The end time of the heat warning may change with weather conditions. Families caring for seniors, young children or people with chronic illnesses should check weather alerts and public facility schedules each day rather than relying on outdated hours.（LJI by Yuanyuan）
