Here's everything known about the earthquake that shook parts of Ontario on Monday

A 3.8-magnitude earthquake struck Buffalo, New York, early Monday morning, and the shaking was felt as far away as the Greater Toronto Area (GTA).

Previously reported at 4.2 magnitude, the event has since been downgraded to 3.8, but the effects were still noticeable on the Canadian side of the border when the quake struck around 6:15 a.m. Monday.

The strongest quake ever recorded in the region registered a magnitude of 5.5 in August 1929, but you don't have to go back quite so far to find notable earthquakes in the Toronto-area history books.

A magnitude 5.4 quake centred just south of Lake Erie, shook Southern Ontario in September 1998, which was the last moderate magnitude earthquake to hit the region.
