When the Canadian economy is weak, when you are in a recession, fiscal policy can be very effective in helping mitigate the degree of impact of the business cycle.
The Canadian economy in 2014 suffered a very severe commodity shock. Parts of the country were driven into recession. In 2015 economic growth was below 1%, and in 2016 economic growth was only 1.3%. We were below potential. That meant that the slack in the economy was increasing and so there was scope for monetary and fiscal policy to provide support.
However, this year the Canadian economy is likely to have the fastest growth in the G7. Economic growth is likely to be over 3%. This is one of the reasons the Bank of Canada has now reversed the half point of rate cuts it provided in the fallout of the commodity shock. The Bank of Canada has scaled back the amount of monetary stimulus it's providing.
Looking forward, I would argue that the Canadian economy does not need fiscal stimulus at a time when the slack in the economy is being eaten up. Having said that, I do believe that we have an infrastructure deficit. I do believe a lot of our infrastructure was put in place in the 1970s, 1980s, and 1990s. It's old. It needs refurbishment. It needs replacement.
I think that public investment in infrastructure can be a catalyst to private sector investment. In point of fact, investing in core economic and social priorities has merit, but ultimately you have to be fiscally responsible, and that means returning to balance. I don't think the government should eliminate the deficit in one year—I think it would be too much of an economic adjustment—but ultimately, I think balancing the books is called for.
