The Building and Technical Standards branch would like to advise stakeholders of a new Ministerial Interpretation. Effective September 21, 2026, a Ministerial Interpretation titled “Carbon Monoxide (CO) Detectors Installed In Lieu of CO Alarms” is available.
This interpretation is related to Henry’s Law, which comes into force in Saskatchewan on November 1, 2026. Introduced on May 5, 2026, Henry’s Law requires all residential suites in Saskatchewan, regardless of their location in the building, to have a carbon monoxide (CO) alarm installed. The enhanced regulations are named in honour of Henry Losco, who passed away from carbon monoxide poisoning in Regina in December of 2025.
The interpretation provides additional flexibility for building owners by permitting the installation of CO detectors in lieu of CO alarms in certain circumstances. In particular, it provides an alternative compliance option for owners of buildings equipped with fire alarm systems, allowing interconnected CO detectors to be used to satisfy the requirements of Henry’s Law.
Additional information regarding CO alarm requirements, including installation locations, is available in the following advisories:
Advisory: Carbon Monoxide and Smoke Alarms – Protecting people in their homes
Advisory: Carbon Monoxide and Smoke Alarms – Multi-Unit Residential Buildings
Please feel free to contact the Building and Technical Standards branch if you have any questions regarding this interpretation or Saskatchewan’s code requirements for carbon monoxide alarms.
