Ontario has added 729,000 net new jobs since the depths of the worst recession since the Great Depression, almost all of them full time.  This self serving piece of slag from the Fraser Institute points out that 75,000 manufacturing jobs left specifically because of electricity rates.
They neglect to mention the differential from all the jobs added across all other sectors and they willfully leave out all the other problems manufacturing has to deal with such as automation, globalization, exchange rates, low productivity and extremely low labor costs from foreign competitors.
Not one province in Canada has more manufacturing jobs now than it did 10 years ago. But the Fraser Institute wants you to believe Ontario's decline is singularly due to electricity rates and nothing has replaced the losses. That makes it a  false narrative.
