Prior to the enhanced protocol or MOU that we signed with Transport Canada, Transport Canada did have access to limited databases. Through the 2009 MOU we agreed with a funded initiative that provided previously unavailable access to databases. So it's more comprehensive searches compared to what we were doing from 2004 to 2009.
This provided a greater access to information that would help Transport in its decision-making. For example, previously we probably checked about two databases, based on various risk factors. Today we check no fewer than five, and if there's any adverse information, we go deeper into additional databases. That's the enhancement.
