New laws regarding carbon monoxide alarms have come into effect in Ontario. To ensure the safety of families, the government has now made it mandatory for more homes and buildings to install carbon monoxide alarms.

Carbon monoxide is a deadly gas that has no smell, taste or colour. It can cause serious health problems and even death if not detected in time. Alarms are required in homes with fuel-burning appliances, furnaces, stoves or fireplaces. Alarms are also required in homes with attached garages, as smoke from vehicles can enter the home. Apartments, condos, hotels, motels and retirement homes must also comply with these laws.

Landlords and building owners are responsible for installing alarms in the correct locations. Alarms should be installed near bedrooms and other areas of the building where the gas could spread. Officials said the new changes will help prevent accidents caused by carbon monoxide. The fire department has also told residents to check the alarms regularly to make sure they are working properly.
