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

This bill primarily affects Ontario municipal governments and their treasury departments, which must include extreme heat awareness materials with every property tax bill they send out. Any Ontario property owner — whether a sole proprietor running a small shop, a landlord managing rental properties, or a larger commercial enterprise — will receive these materials with their tax bills but faces no new operational obligations. Municipal treasurers in cities and towns across Ontario, including Toronto, will need to coordinate the printing and distribution of these materials, adding a modest administrative and mailing cost to their tax billing processes. The bill does not impose direct compliance burdens on private businesses, though municipalities may see increased costs in their billing operations.
