Its weird they didn't include the costs of things like the NDPs cut to small business taxes and the innovation tax credit, but they include things like fixing EI, the costs of which would be payed for by the EI fund, and Mail Delivery which comes from Canada Post, not general revenue.
Also it doesn't account for cap and trade, which would add more then enough revenue to pay for the Enviromental Costs, plus disaster prevention and more besides.
It also doesn't include elimating the stock loophole or the programs to help poor families that money will be spent on.
