I think that we just had an EARTHQUAKE in Toronto! The whole office shook for nearly 20 seconds...
EDIT: Yep, we did but I can't get any details because all of the news website in Eastern Canada just crashed apparently. Someone on Twitter claims that it was 3.0 and felt from Ottawa to upper New York State.

This must have been a webcam and on a higher floor in an office building. We didn't witness that much rocking and it felt more sustained than that in our offices...
