You might want to look elsewhere. Air Canada Regional Airlines is the major Dash 8 operator these days, and I don`t think they care one way or another if you have a rating. They have a number of people interviewed and approved, who are in the holding pattern with no EFC for a course date. Blame Osama and the economy for that.
There are a few more Dash operators-- one is Air Inuit, another is Air Creebec, a third is Hawkair and finally Hydro Quebec. Any of them have only a few Dash`s. Pre-Sept 11th I saw ads for short term contracts for Dash 8 people-- 500 hours on type seems to be the mins for a FO.
