The downgrade is almost entirely from external forces, as has been our series of downgrades. There has been a global disappointment, which has pushed down everybody's forecast, over and over again, over the last five or six years, in our case, primarily the U.S. On the edge of that, it's even a little less for us, because our share of exports to the United States has been gradually declining. That's just to put it into context.
In terms of how much growth we expect from the fiscal plan, that remains something to be monitored. What we have built in is approximately 0.5 percentage points this year, and one percentage point on the level of GDP by the end of the next fiscal year. Of course, that remains to be seen, because there are no signs yet in the data we have available. It's a little early. We had the child benefit in July, so as we go through the rest of this year, we should see something in the retail sales data.
Importantly, there is no category in the StatsCan publication that is going to tell us, “This came from fiscal expansion.” It will tell us how much of a contribution the government made to GDP, but that won't be mapped directly to the fiscal plan. It's important that we understand that.
Years from now, we will be analyzing this episode, and the economists will figure out how much actually came, but that's very common. We referred to the U.S. infrastructure spending, where the components on roads and bridges delivered over an eight-year period three times the initial investment. That came both on the level, because of the spending, and because of the fact that those roads increased the potential growth rate for businesses to move their stuff around.
