Smoke Alarm Status in Home Fires
Ontario Smoke Alarm Status in Residential Fires
1991 -- Canadian Mortgage and Housing Corp (1991) reports
"In 1987, 277 people died in fires in one and two family dwellings across the country - the vast majority of them in homes built before 1980….
In fact, since the total number of homes had grown, this represents a drop in fire deaths to 4.5 per 100,000 homes in 1987 from 7.9 in 1980. There are a number of reasons for this improvement in safety… but is generally agreed that one major difference is the advent of inexpensive battery-operated and wired in place smoke alarms.
New homes, which have been required by building codes to have mandatory wired in smoke alarms since early in the 1980's, are much safer (estimated 1.4 deaths per 100,000) than the general housing stock."
1975 -- Ontario homes required to have smoke alarms outside sleeping areas
1980 -- Ontario fire death rate 30.9 per million population.

Fire departments are asked to report on the presence and operation of smoke alarms and suppression devices in every structure fire they attend.
The data collection was revised in 2009 to accommodate new smoke alarm regulations and to make the reporting more accurate. The results in 2009 were consistent with prior years, prior data collection.
The report covers smoke alarms on the floor/suite of fire origin of residential property fires with loss - $ loss, injury or fatality – excluding residential non structures (tent) and detached garages, from 2010 to 2019.
Residential Loss Fires: Smoke Alarm Operation
