What was that around 9:45 this morning? 

No, you weren't imagining it.  It was an earthquake.

A 5.1-magnitude earthquake in Ontario, Canada was felt across upstate New York.

Canada's government agency that monitors earthquakes says the quake occurred at 9:43 a.m. Friday about 13 miles northeast of Shawville, Quebec, about an hour's drive outside Ottawa. About 10 minutes later, there was a 4.4-magnitude aftershock.

Local media outlets in northern New York say people in communities along the St. Lawrence River and as far east as Lake Champlain reported feeling their homes shake. There are also reports from residents of Buffalo and surrounding suburbs who say they felt their houses sway and the ground shake for less than a minute.

There are no reports of damage.

It's been about three years since there was an earthquake of any real magnitude that could be felt in Western New York.

Did you feel it?
