If you can point me to a list of those that have left and the reasons for their leaving, I would appreciate it.  Cat pulled out from London because workers would not take a 50% cut in pay.  Kelloggs closed an old plant and expanded one in Bellville in 2013 when the reason was the dollar being near parity (it also closed plants in Australia and the US at the same time).  GE is opening a new facility in Welland recently and Dr. Otetker opened a frozen pizza plant in London in 2014.  And the car companies agreed to increased investment in Canada as part of its settlement with the union.  Plants come and go all the time.  You have oversimplified Nick.
