I'd like to know what happened after the CSR announced he was on The List.
If nothing else (no other individuals summoned), the CSR probably should have said he was a randon selectee; they are notoriously loose with their definitions.
If he really is on The List here's a couple of sites to check out:

http://www.tc.gc.ca/corporate-services/oor/menu.htm (official (hah!) watchdog)
