Unless the deal means Canadian governments and businesses who currently purchase from foreign sources will now purchase from Canadian sources. This deal won't amount to any new dollars in the Canadian economy.

What will happen is a company in Ontario might get work in Manitoba because it has the lowest bid beating out a company in Manitoba. Which equals zero new dollars entering the Canadian economy. More like a shell game of shifting money from one region to another. In fact the increased competition on a national basis will likely reduce the money within the economy.
