There are 140 safety inspectors throughout the country who look at all aspects of the system. Some of them are assigned to marine transportation.
In the area of air transportation, for example, inspectors do infiltration tests. That means they try to get through search points with prohibited objects, and carry around passes to check how the airports intercept people with false passes or they check on the security aspects of the various tenants in airports and the access points to airports.
I should mention that since the fall of 2001, the number of people working in the area of safety at Transport Canada has gone from 165 employees to 400, 140 of whom are field inspectors.
