It's good. A key element was when the port state control regime came out about 20 years or so ago. It's been a very big driver of improvement in the quality of ships and the elimination of substandard shipping. The last data published on Transport Canada's website, for example, showed there were 1,033 inspections in 2011, including 358 tankers. There were 431 deficiencies, out of which seven were for dangerous goods and 63 were ISM Code ones. This led to 34 detentions, ships that were detained, of which two were tankers. That gives you an idea of what it means.
Actually, the safety record is very good and is getting better and better. For some trade, especially the tanker trade, we've probably reached residual risk. At some point—I don't remember when it was; I think it was in this committee at the previous hearing—we had the data from ITOPF, an international organization gathering data on that, and it showed that really, the number of spills worldwide is at a very residual level.
