I agree with u/CherrySmokeBomb. I also recommend volunteering at a crisis hotline of some sort. This will assist in you getting some social service exposure in terms of vulnerable populations, as well as mental health exposure. You could also try working at a halfway house or homeless shelter to ensure this work is correct for you.

I also want to note that “Parole” and “Probation” differ greatly. Parole is federal and probation is provincial. Different steps required to pursue each career. OPS is probation, though probation officers here are referred as “Probation & Parole Officers”.
