We don't have that information. I'm glad you asked the question. I think it may be a question that would be useful to pose to the Canadian Food Inspection Agency. It would depend on their ranking of risk. For the airlines themselves, there are four major airports at which the inspections take place. They're done on a regular basis.
For the bottled water part of the report, during the course of the 2007-08 audit, there were 78 inspections in all provinces in Canada. There were no major problems that would actually change the level of risk for bottled water.
