Annual review of Ontario seismicity
The fractal upper limit for most of the zone is probably M6. The main question is the boundary fault under Hamilton. Is it more uniform? Can it produce an M7? I think the answer will be found in Oklahoma, which has exactly the same band, and same pattern, activated by deep injection. They are still injecting, Come Hell or High Water, and the boundary zone is right under the city. They'll most likely get it before Toronto.
As you can see, water is the essential element to earthquake life. The Grenville Front is only active in Georgian Bay and a bit of Lake Huron. And we know what they plan for that megathrust right at Bruce!
