From what I have understood the multiple of every well-invested dollar in the ROF , is over 20 times, not in takes, but in economic output/ revenues. Source for this snowball- effect is historic based evidence from different ROF reportings including the Ontario Chamber of Commerce. Keynes is right that authorities need to invest specifically iat times such as current state of economy, there is no better alternative. Useless to say that it builds debt, substantiated by the figures, it would be no more than an investment with high return due to increased economic activitty. Leakages are allowed to certain extent. As stated, the business case for the ROF is set, political willpower now existing as one question: What will happen if you do not invest ? A far worse political and economic picture will occur, in fact is already taking place if nothing is done. More clear it cannot be made, the details and the main priorities need to be well distinguished in the political decision-making to add to the test performed on so many instances since the rise of the Canada. How did we get there, being fearless, sense of reality and sense of humor (fun).
