It was good to see Minister of Immigration John McCallum who is an economist and the Minister of Finance Bill Morneau defend the Keynesian Liberal plan to use much needed new  investment infrastructure to promote economic growth, employment and innovation in the Canadian economy as a counter cyclical force to the slower economic growth that is emerging and that is predicted to accelerate by the parliamentary budget office and the IMF. As McCallum explained the slower growth is precisely why one needs to invest and it provides even greater justification for deficit financed investment in infrastructure. Mr. Morneau concurred in this judgement. The amount currently spoken of some 10 billion dollars in the first year is modest in relation to the GDP of 1.98 trillion Canadian dollars. The current anticipated deficit is 0.2 % of the GDP. It will initially rise by a small amount but as the employment created by these investment circulates throughout the economy affecting other proposed investments and states of confidence the impact will be multiplied modestly and the increase in the deficit even in the medium run will be lessened.In any case the parliamentary budget office is projecting a falling debt to GDP ratio which at the present is still historically quite low.It projects the debt to GDP ration falling from 31% to 26.1%. The strategy combined with the tax cut for the middle class should help diminish currently unspent quasi hoarded cash balances in the private and corporate sector and restore optimism  in expectations of private consumers and business investors.If the economy slows a great deal further and faster one might want to spend more of the allocated amount faster by front loading it  and consider expanding the program.
