Excuse me while I pick my jaw up off the floor:

Being a member of a terrorist organization won't necessarily land someone on Canada's no-fly list, The Canadian Press has learned.

Proposed criteria would limit inclusion on the roster to those who pose "an immediate threat to aviation security," Transport Canada internal briefing notes say.
...
"You cannot be put on the list on the sole basis that you're a member of a 'terrorist group,'" the source said. "In addition, you have to be a demonstrable threat to aviation safety."

In other words... being a terrorist doesn't make you a threat.  In other news, Webster's dictionary has decided to place an illustration of what a typical terrorist looks like next to the definition.  So who would be included in this list?

People would also be considered for the list if they have:

- Been convicted of one or more serious and life-threatening crimes against civil aviation, meaning a public air carrier, in Canada or abroad.

- Attempted to commit an offence or offences related to civil aviation.

- Been convicted of one or more violent criminal offences and have a motive to attack or harm an air carrier.

- Been determined, based on their behaviour or actions, to constitute an immediate threat to civil aviation.

Which for the terrorists is mighty damn convenient, since they're rarely ever convicted of an offence related to civil aviation.  They kill themselves while they kill everyone else on the plane!  Via Protein Wisdom.
