Felt it in Waterloo, too, about an hour west of Toronto. At the time, I was on the phone with a guy in a Toronto suburb who said, "Did you feel that?" That's when I knew for certain it was an earthquake.
This is the first earthquake I've ever experienced (at least the first in which I was consciously aware of it being an earthquake).
No injuries or damage here, that I can see. But I am noticing cracks in my buidling and I am wondering whether they've ALWAYS been there, or ...?
