Enhanced carbon monoxide alarm requirements took effect today.

Henry’s Law strengthens carbon monoxide (CO) alarm requirements for all multi-unit residential buildings in Saskatchewan.

Announced earlier this year, Henry’s Law expands existing CO requirements by mandating alarms in all residential suites, regardless of their proximity to fuel-burning appliances within a building.

In a news release from the province says, “Saskatchewan implemented one of the nation’s strongest CO alarm requirements in 2022 and Henry’s Law is the latest addition to keep residents safe.”

Government Relations Minister Eric Schmalz said, ” We are grateful to Henry’s family for their courage and advocacy in support of these important changes.”

The changes were introduced following the tragic death of 11-year-old Henry Losco, who died in December 2025

Henry Losco died from carbon monoxide poisoning while in the family’s suite in the apartment building and his father was taken to hospital in critical condition. Fire officials say the incident was caused “by a boiler that experienced significant internal failure, resulting in a substantial release of carbon monoxide.”

Henry’s parents, Marina Hills and Sergio Losco, have been outspoken in their call for stronger regulations and CO awareness. Marina Hills says “Safety starts at home.”
