As I said earlier, in the past Transport Canada would send in a team of subject matter experts. They would go physically into the airfield, boots on the ground, and conduct an inspection based on specific standards and regulations. They would identify deficiencies found, and those deficiencies would have to be addressed by the specific airport authority within a predetermined time frame.
With the implementation of SMS now, again, I don't see it as less oversight. I see it more as that the process has changed. With the implementation of SMS, which occurred over a four-year period, and significant consultation with Transport Canada, airports now conduct inspections and maintenance of their airfields on a daily basis. Throughout that process—a proactive process—they identify deficiencies and areas where corrective actions are needed, and that feeds through a specific process.
As Mr. Maybee mentioned, every three years the airport authority itself will have an independent auditor come in and audit our processes to make sure we're picking up on safety issues and concerns, hazards, and so on. Transport Canada really audits from the same perspective, the oversight of how those things are working internally.
