Without details, it's impossible to know.
Did you elect to take the PiL? If so, no severance (since you got the PiL instead). If not, 1 week pay per year (less NES & ED&T) through Feb 2012, paid at your rate of pay on release.
Are you a contributor to the CFSA, part I or part I.1? If so, what you receive as a pension, or as pension options, depends on your years of service, age, and whether or not you bought back prior service.
