What's interesting about this particular earthquake is the measurements of seismic waves traveling through the continental US.

I've not seen that before, but presumably similar measurements are made for other earthquakes.

It looks like it passed through S. Ontario around 4:37PM local time Monday.

Am I able to deduce what effects, if any, we ought to have experienced here?

It would probably be unnoticeable among all the other 'noise' from normal, everyday activities, e.g., transportation.

completely unnoticeable by a person, regardless of background noise levels, only recordable on sensitive seismic recorders.
It was just too far from the "lower48" to be felt by a person

this was my recording of it, on my seismo, here in Sydney, Australia.
