When was the last time you tested your smoke alarms?
If you can't remember, today is the perfect day to check.
September 28 is Test Your Smoke Alarm Day. It’s part of a province-wide campaign by Ontario’s Office of the Fire Marshal to raise awareness about the importance of testing and installing smoke alarms.
Why This Day Matters
Test Your Smoke Alarm Day is more than just another awareness campaign. In 2022, Ontario experienced the highest number of fire fatalities in 20 years, with 133 fire deaths. In too many of those cases, investigators found there were no working smoke alarms.
In response, Test Your Smoke Alarm Day was launched in 2023.
Working smoke alarms are your first line of defense, giving you and your loved ones precious seconds to escape in the event of a fire. That's why the Fire Marshal calls testing your alarm "a thirty-second life saver."
Your Smoke Alarm Safety Checklist
Take a few minutes today to walk through your home with this checklist:
Coverage: Do you have a working smoke alarm on every level of your home and outside all sleeping areas?

Testing: Have you tested each alarm recently? Press the test button on each unit to ensure it's functioning properly.
Batteries: When did you last replace the batteries? They should be changed at least once a year (preferably twice), and whenever the low-battery chirp sounds.

Age matters: Check the manufacture date on the back of each detector. If any are 10 years old or older, replace them immediately—even if they still seem to work. Sensors degrade over time and may not function reliably.
Hardwired units: Even if your alarms are wired into your electrical system, they still need regular inspection and maintenance. They contain components that can fail, including sensors and battery backups.

Smart alarms still need to be tested: Press the button on the device twice to activate a manual test. The test will start with a countdown. You should hear the alarm's speaker and horn to confirm it's working.
What to Do When You Find Issues
Insufficient coverage? Purchase and install additional detectors right away. Every level of your home and every sleeping area needs protection.
Failed the test? If a detector doesn't work even after replacing the battery, it needs to be replaced entirely.
Are any of your smoke alarms 10 years old or older? If so, it’s time to replace them—even if they still seem to work.
Replacing hardwired units? Be aware that mixing brands often doesn't work. All interconnected hardwired units should be from the same manufacturer with compatible signalling. If you can't find an exact replacement, it's often best to replace all interconnected units together.
Can't reach high ceilings? Try a broomstick to reach the test button. To check the date you may need a step-ladder and someone to help you or to hire a handyman.
Make It a Monthly Habit
Ontario’s Fire Marshal says, “Testing your smoke alarm is a thirty-second life saver.” The best way to stay safe is to make it a monthly habit. You can sign up for reminders at Saved By The Beep
