Growing concerns over extreme summer temperatures have sparked renewed calls for mandatory air conditioning in daycare centres across Canada, as infants and toddlers continue to face uncomfortable and potentially unsafe conditions during heat waves. Parents, childcare workers, pediatricians, and advocacy groups argue that maintaining safe indoor temperatures is becoming increasingly important as climate change contributes to more frequent and prolonged periods of extreme heat.
Parents say some daycare classrooms become uncomfortably hot during the afternoon, particularly in older buildings that lack central cooling systems or adequate ventilation. They worry that prolonged exposure to high temperatures can affect children’s health, comfort, sleep, appetite, and ability to participate in daily learning and play activities. Childcare workers also report that excessive indoor heat can make it more challenging to care for young children throughout the day.
Health experts emphasize that infants and toddlers are especially vulnerable to heat-related illnesses because their bodies do not regulate temperature as efficiently as adults. Young children may not recognize the early signs of overheating or be able to communicate symptoms such as dizziness, fatigue, or thirst, increasing the risk of dehydration, heat exhaustion, and other heat-related complications.
Many daycare operators currently rely on portable fans, shaded outdoor play areas, increased hydration breaks, cool indoor activities, and adjusted schedules during hot weather. However, advocates argue that these measures provide only temporary relief and are not an adequate substitute for air conditioning during prolonged heat waves. They are calling on provincial governments to establish mandatory maximum indoor temperature standards and require licensed childcare centres to install effective cooling systems.
Daycare operators say the cost of installing and maintaining air conditioning can be significant, especially for centres operating in older buildings or on limited budgets. Sector representatives are urging governments to provide funding or infrastructure grants to help childcare providers upgrade their facilities without passing additional costs on to families through higher childcare fees.
Public health experts note that ensuring a safe indoor environment is becoming an increasingly important aspect of childcare as Canada experiences warmer summers. They recommend that daycare centres regularly monitor indoor temperatures, encourage frequent water intake, reduce strenuous physical activity during periods of extreme heat, and develop heat-response plans to protect children and staff.
Although several provinces have issued heat-safety guidance for licensed childcare facilities, there is currently no uniform national requirement mandating air conditioning in daycare centres. As extreme heat events become more common, advocates say governments should review existing childcare standards to ensure facilities are better equipped to protect the health, safety, and well-being of Canada’s youngest children.
