Despite the frosty weather, the clocks will still spring forward at 2:00 a.m. Sunday morning.

At that hour, the clocks will move ahead to 3:00 a.m., depriving us all of one hour of sleep.

For those who enjoy the nightlife, bars, taverns, clubs and restaurants will stop serving alcoholic beverages when the clocks shift.

Fire protection services strongly encourage Montrealers to check their smoke alarms and replace the batteries the day the clocks change over.

"It's a way to remind us because we have to change the hour," said Louise Desrosiers, head of prevention at the Montreal Fire Department. "So by the way, when you're up there, you can look out for your smoke alarm to make sure that it's working."

Desrosiers also noted that smoke detectors must be replaced every 10 years.

In 2016, 11 Montreal residents died in fires and, in most cases, the smoke alarms were not functional. Roughly 25 per cent of Montreal homes do not have properly functioning smoke detectors.

“When you wake up, you’re standing up in the day time, you’re probably going to smell if something happens inside your apartment. But when you’re sleeping, you don’t smell as well," said Desrosiers. "That’s the problem, if you fall asleep and there’s a fire starting in the kitchen or somewhere else in your apartment, you don’t have much chance of getting out alive if you don’t have a smoke alarm to wake you up.”

On Saturday, students from Montreal’s fire department academy will go around the city to raise awareness of the importance of smoke detectors. In addition to checking the devices and giving information, they will be handing out new detectors and batteries.
