Arrow BulletHot Weather Guidelines: Advice to Housing Authorities and Landlords

Peel Health recommends the following steps to be taken to prevent heat related illness:

  1. Develop policies and procedures to maintain building structures and equipment to maintain comfortable temperatures.

  2. Monitor daily heat advisories.

  3. If possible, provide a central cool room or space for tenants and visitors.

  4. Provide and post information in common areas for residents.

    For example,

    • Residents without air-conditioning should keep windows open at night during cooler hours and have shades or blinds drawn during the day.
    • Residents should use the stove or oven less to maintain a cooler environment in their unit or room.
    • Provide a list of local facilities close to your building that are air-conditioned and advise people to visit them.

  5. Check on elderly residents that live alone, and those who are physically or mentally challenged to ensure they are cool and properly hydrated.

  6. Management should be aware of the signs of heat cramps, heat exhaustion and heat stroke (see reverse for heat illness signs and treatment). Keep this information handy during the summer months.

  7. Take immediate action if you find anyone exhibiting signs of heat exhaustion or heat stroke, follow treatment guidelines from the Region of Peel’s website for immediate response, and call 911 for anyone who exhibits signs of increased confusion and/or unresponsiveness.
