You can still get onto a Dash 8/Saab at a substantial number of Airports with no security whatsoever.
Looks like that might continue to be the case for the foreseeable too. For whatever reason, the minister's White Paper imposed screening requirements on 30,000KG Turbo Props (any of those about?) almost immediately with 20,000KG by 2014. Saabs and Dash 8 (except Q400) still come in at below that limit.
