In a release, the Canadian Nuclear Safety Commission said the quake had no effect on that site, its National Research Universal Reactor, or any other nuclear facility in the country. A release from Chalk River confirmed that a site walkdown showed no damage at the labs.

According to the Canadian Broadcasting Corp., the quake could be felt as far away as Toronto and Cleveland.
