Hamilton councillors have approved a pilot program requiring landlords in downtown Ward 2 to maintain at least one room below 26°C during summer, marking the first such initiative in Ontario. This pilot, inspired by rising temperatures due to climate change and set to run through September 2028, aims to address extreme indoor heat affecting renters. While seen as groundbreaking, tenant groups advocate for broader application, while landlord associations seek further study before implementing the policy citywide.

Story summary
Hamilton, Ontario is set to become the first city in the province to pilot a new bylaw requiring landlords to keep at least one room in each rental unit below 26°C during extreme summer heat. This initiative stems from a growing concern over the increasing frequency and intensity of dangerous heat waves due to climate change. The pilot program, approved by local councillors, will initially apply to Ward 2 in downtown Hamilton, an area where most residents are renters. Health Canada recognizes this temperature threshold as safe for indoor living.
The results of this pilot will be closely monitored by other cities grappling with similar issues, such as Toronto, which is also exploring ways to protect tenants from extreme heat. The city’s interim manager, Mike Zegarac, emphasized the importance of addressing the impacts of climate change on residents' well-being and noted that recommendations for a broader rollout are expected in early 2029.
While Ontario’s tenant laws currently mandate heating but not cooling, this pilot represents a significant shift in policy to ensure renters’ safety during extreme heat conditions. ACORN Hamilton, an advocacy group, has been pushing for such measures as part of their efforts to address the impacts of climate change on housing and public health.
