As you say, it is currently reciprocal. The documents I've read have said that it's a reciprocal agreement. I'll tell you that right now.
For my membership to get their Transport security clearance, we're waiting anywhere from six months to a year. If you add in the reciprocity part of this agreement whereby Transport Canada now has to go and investigate 70,000 longshore personnel plus, or 10,000 or however many they have to do, that's going to slow down our process.
