It’s true, I moved to the San Francisco, a city that sits on one of the most active fault lines in the world. Toronto, not so much - although it has had two tremors in the last year. Since experiencing two significant shakers in one day (October 20), I have become fascinated with this website from the US Geological Survey: Where, When, How big, etc. My only beef with it - it doesn’t tell you when, or where, the next one will happen.

Also, apparently there is predictions for a big one coming soon. YIKES!

(Oh, and I am not ashamed to admit it, the second one I felt in my 11th floor apartment made me feel very unsettled for quite some time after.)
