Health Canada warns that Gedsffati Plug-in Combined Smoke and Carbon Monoxide Alarm previously available on Amazon.ca may fail to operate

Health Canada's sampling and evaluation program has determined that the product may not meet the Residential Detectors Regulations in Canada. 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 or fire, 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.
