The parents of an 11-year-old boy who died from carbon monoxide poisoning in a Regina apartment have filed a lawsuit against four companies, alleging negligence in the incident that also hospitalized the boy's father.
On December 19, 2025, Henry Losco was found unresponsive in the family's apartment on the 1800 block of Albert Street and was pronounced dead at the scene. His father, Sergio Losco, was also in the apartment but survived after being taken to hospital.
Sergio Losco and the boy's mother, Marina Hills, are listed as plaintiffs in the statement of claim filed on May 29, 2026. Henry Losco is also listed as a plaintiff through his mother as his administrator, as some damages are sought on his behalf. The amount of damages sought is not specified, with losses to be proven at trial.
Defendants named in lawsuit
The lawsuit names four defendants: D.R. Anderson Holdings Inc., which is said to own the building; Skyward Living Properties Inc., the property manager; Anderson Builders Group 1989 Inc., responsible for construction and renovation; and Ariston Canada Inc., which manufactured the building's boilers.
According to the court document, two newly-installed boilers were commissioned on December 18, 2025, the day before the fatal incident. On January 30, 2026, Regina Fire Chief Layne Jackson publicly confirmed that the carbon monoxide leak was caused by a critical failure in a boiler at the premises.
Allegations of negligence
The suit claims each defendant had specific responsibilities. The boiler manufacturer was responsible for building safe machines; the builders were responsible for safe installation; and the owner and property manager were responsible for ongoing operation, maintenance, and inspection.
In the days leading up to December 19, 2025, residents made repeated complaints to the defendants about issues with carbon monoxide detectors in the building. The document asserts that the defendants were placed on notice of a potential carbon monoxide hazard but failed to address it.
Workers were observed physically removing detectors from the building, claiming the detectors needed to "air out." One resident who called after an alarm was told to open a window and use a fan. The lawsuit alleges failures to call emergency services, issue evacuation orders, notify residents, shut down fuel-burning equipment, inspect gas systems, or contact the provincial boiler inspecting agency.
