Getting married

I work part-time and receive FIS. If I marry and stay working P/T (my boyfriend is unemployed) what benefits would I get? I would loose my O.P.F payment wouldnt I? What benefits would he get? I have a son (not for my boyfriend and dont receive any maintenance.
Thanks in advance

You would lose your One-parent Family Payment as you would no longer be a one-parent family. As for FIS, his Sw payments would be added to your income for assessment. See here
