Combined Smoke, Combustible Gas & Carbon Monoxide Alarm Recall (July 2026)

What was recalled

This recall involves the Combined Smoke, Combustible Gas & Carbon Monoxide Alarm with model number HD18-CGS. The model number can be found on the label on the back of the product and on the front of the product packaging.

Why it was recalled

The Residential Detectors Regulations require that smoke detectors, heat actuated fire detectors and smoke alarms in Canada meet the applicable Canadian standards.  The product does not have a Canadian certification mark and it is unknown if the alarm operates in the presence of smoke, posing a potential fire hazard.

Health Canada reminds consumers that products that do not have a recognized Canadian certification mark may not meet Canadian performance standards and could fail or operate incorrectly. This could pose a risk to consumers who may not be alerted to a fire incident in their home. For more information on what to look for when purchasing a smoke alarm or detector, see Health Canada's Consumer Information -  When purchasing smoke or carbon monoxide alarms, look for a Canadian certification mark.

As of June 22 nd , 2026, the company has not received reports of incidents or injuries in Canada.

What to do

Consumers should immediately stop using the recalled product and dispose of it according to municipal hazardous waste guidelines. Consumers should replace the recalled product with one that bears a Canadian certification mark.
