Negligence alleged in lawsuit filed by family of young carbon monoxide victim

The family of an 11-year-old Regina boy who died of carbon monoxide poisoning in December 2025 has now filed a lawsuit alleging negligence by four companies.

Henry Losco’s parents, Marina Hills and Sergio Losco, filed a statement of claim dated May 29, 2026 against D.R. Anderson Holdings, Inc.; Skyward Living Properties, Inc.; Anderson Builders Group (1989), Inc.; and Ariston Canada, Inc.

No statements of defense have yet been filed and the claims have not been proven in court.

The family is seeking general, punitive and aggravated damages, citing “the traumatic discovery by Marina Hills of her deceased son and unconscious husband, the forced displacement from their home, and the severe emotional and psychological suffering endured by the plaintiffs” in the statement of claim.

The statement alleged that in the days leading up to Henry’s death on Dec. 19, 2025, residents of the apartment building at Albert Street and 11th Avenue made repeated complaints to the defendants, including the building’s maintenance staff, about issues with carbon monoxide detectors in the building, but that the response was to remove the detectors to air them out.

Earlier on Dec. 19, it’s alleged another resident with his own carbon monoxide detector found it going off, but that maintenance responded by telling him to open his windows and use a fan.

That same afternoon, Henry was feeling ill and went to lie down. His mother later found him “ashen and stiff,” while Sergio was unconscious in the living room.

“His death was entirely preventable had the Defendants maintained functional carbon monoxide detectors throughout the building, properly investigated the carbon monoxide alarm that sounded in another tenant’s unit earlier that afternoon, and evacuated the building,” the statement of claim alleged.

Regina’s fire chief later confirmed a leak from a boiler was responsible for the carbon monoxide in the building.

The court document accused D.R. Anderson Holdings of negligence as the building’s registered owner; Skyward Living Properties as the property owner; Anderson Builders Group as the company that installed the boilers; and Ariston Canada, the maker and supplier of the FTG-series boilers.

Ariston, formerly known as NTI Boilers, has issued a safety notice for the boilers in question.

“Under certain installation conditions, delayed ignition may occur in the Boilers, which could contribute to damage to exhaust venting components and the potential release of combustion products, including carbon monoxide,” the safety notice says.

Henry is listed as a plaintiff in the case, with mother Marina Hills as administrator on his behalf. Hills and Sergio Losco are also defendants.

The statement of claim did not specify an amount for damages, only stating “an amount to be proven at trial.”
