An earthquake centred northwest of Ottawa has rattled buildings and nerves across a wide swath of Ontario and Quebec.

Earthquakes Canada has revised its original report, saying it registered a 5.2-magnitude temblor with an epicentre located about 21 kilometres northeast of Shawville, Quebec, about an hour’s drive outside the national capital.

The original report said a 4.8 magnitude quake was centred near the town of Braeside, Ontario. Less than 10 minutes later, a 4.2-magnitude aftershock was also recorded.

There have been reports of buildings shaking in Ottawa for several seconds; it was also felt in Toronto.

Ontario Provincial Police in Arnprior, Ontario, not far from the epicentre, say they have received no reports of damage.
