At 12:19 am Wednesday morning, a magnitude 4.5 earthquake rattled the Montreal area.
While there have been no reports of any serious damage or injuries, the quake was strong enough to wake people from their sleep. It even sent some scurrying briefly from their homes and onto the streets.
Police officials say the quake prompted numerous calls to 911 and several people also took to Twitter and Facebook to report the shaking, which lasted for a few seconds.
The epicentre was 37 km east of Montreal, but tremors were felt as far away as Ottawa.
According to Natural Resources Canada, the quake occurred in an area known as the West Quebec seismic zone and temblors aren't uncommon in that area.
