We started off in 2013 spending approximately $15 million a year on non-passenger screening. We had a very minimal program at the time, which essentially consisted of a sampling of non-passengers accessing the sterile areas of airports. It was decided by the government at that time, with Transport Canada's regulatory oversight, that we needed to improve our standard of delivery of that service based on the coming into force of the ICAO standard.
To go from $15 million to what will eventually be almost $150 million of annual expenditure required an implementation phase: implementation to hire the screening officers, to purchase the equipment, to train the people, to put the infrastructure into place, to get the airports ready. To do all this, there has been a huge amount of work over the last three years. What you see isn't a delay; it's a planned implementation phase, which is just culminating now, as we reach the maturity of the three-year implementation.
I'm quite proud of what we've been able to do, to go from $15 million to a tenfold increase in three years.
