In Canada there is two plate boundaries. One is on the south west coast and is a convergent and the other runs up the Canadian coast and is divergent. The plate is called Juan De Fuca Plate. I found this on page 30 in our book. The Juan De Fuca is responsible for many of the northern California quakes and all of the volcanoes in Oregon and Washington!
