A mild earthquake rattled through the Montreal area early Wednesday and was felt in the Cornwall area - though many people missed it as they were sleeping or simply didn't feel it.
The 4.5-magnitude quake struck at 12:20 a.m., according to Natural Resources Canada.
The temblor lasted just a few seconds.
The earthquake’s epicentre was near Saint-Hyacinthe, just east of Montreal, and buried some 20 km below the surface.
There have been no confirmed reports of damage.Cornwall was jolted in June 2010, when a more powerful earthquake took place between Ottawa and Montreal.
The 5.0-magnitude quake struck at around midday and was quickly felt by many in the Seaway City. It also caused some significant damage in one Quebec town.
