Ontario Mandates Extreme Heat Safety Notices

Full Title: Bill 29, Turn Down the Heat Act (Extreme Heat Awareness), 2025

Summary#

This Ontario bill would create an Extreme Heat Awareness program. It aims to help people prepare for heat waves and reduce heat-related health problems.

  • Declares the first week of June each year as Extreme Heat Awareness Week.
  • Requires the province to run a website with tips, prevention steps, resources, and FAQs about extreme heat in Ontario.
  • Requires the province to mail the same information every year to households in areas that are not part of a municipality.
  • Requires all municipalities, including Toronto, to include extreme heat information with property tax bills.
  • Most requirements start three months after the bill becomes law.

Expenses#

No publicly available information.

Proponents' View#

  • Heat awareness can prevent illnesses and save lives by helping people prepare before summer begins.
  • Sending inserts with tax bills reaches most households, and annual mailings cover people in unorganized areas.
  • A single, trusted provincial website makes it easier to find accurate information and local resources.
  • Education is a low-cost way to reduce health risks from rising temperatures and more frequent extreme weather.
  • Better public knowledge may lessen strain on hospitals during heat waves.

Opponents' View#

  • Mandating inserts could add printing and mailing costs for cities and towns, with no new funding.
  • People may ignore extra inserts in tax bills; other outreach methods might work better.
  • Some regions already share heat safety tips; this could duplicate existing local efforts.
  • Awareness alone does not fix barriers like lack of air conditioning, safe housing, or transportation to cooling centres.
  • Annual mailings to unorganized areas add ongoing logistics and costs without clear proof of impact.
