Possible incident at Pickering Nuclear Power Generating Station, Canada.

I live within 50 km of this power plant and received this alert on my cellphone*. My first instinct was to check Radmon for nearby data. All OK, so we went back to sleep!
* The cellphone providers in my province are required to send emergency alerts like tornado warnings and child abduction alerts. This alert was sent by mistake during some sort of training exercise. There has been more screwups than actual alerts so far.
