There was an earthquake in Ontario!

I subscribe to a newsfeed that lists all the earthquakes in the world and was shocked today to see that there was an earthquake in Ontario! I didn't even know that Ontario had fault lines. It was apparently magnitude 4.2 as well, so people should have felt it. Seeing as it was only a few kilometers outside of Owen Sound I wonder if any of my family felt it (that would be an indirect way of saying "post a comment").
