Smoke Alarm Status in Home Fires
Ontario Smoke Alarm Status in Residential Fires 2011 to 2015
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.”
