Of course, yes, productivity gains. Productivity is always an issue for the Canadian economy.
As you heard from the governor, recently we have seen an increase in productivity. Whether it is sustainable over time or not is the major question. Certainly it's not sustainable at the rate we have seen in the past few quarters, but definitely this is a major issue for the economy. It requires investment and better export performance in the economy. All those things, obviously, are challenges that any economy faces. How you resolve them, how you achieve that growth, is another question that I cannot answer.
