The concept of cheap electricity to build industry is nothing new. Adam Beck built Ontario Hydro as a method to produce cheap electricity to build Ontario's industrial base. For the past 40 years Ontario Governments have been milking the profits from Hydro for their pet projects and instead of curbing government spending the Liberals are jacking up rates.  

As a consequence hydro rates are another form of tax on business and people of Ontario.  Businesses have a choice. they leave a high tax jurisdiction.
