When you analyze the economic costs, the amount is about $8 billion, but when it comes benefits, the amount is about $6.4 billion in the area of health. You say that this represents only a fraction of the benefits that Canadians will enjoy.
I would like to know why you account for all of the economic costs, whereas you only consider a fraction of the benefits. Might we conclude that the benefits, as a whole, would represent a higher amount than the economic costs? Have you broken down the benefits in a way that would allow you to determine if they represent only a fraction of the advantages?
