Wolf Shield Optical Smoke Alarm recalled due to potential failure to operate - Canada.ca

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 April 1, 2026, the company has received no reports of incidents or injuries in Canada.
