Corrections does not decide when prisoners are released.
That is determined by the sentencing laws, the sentencing judge, and the Parole Board.
The following table details when prisoners become eligible for release or parole.
| Sentence | Eligible for release |
| Less than two years | Automatically released on conditions after serving half of their sentence |
| More than two years | Eligible for parole after serving one-third of their sentence or at the end of any non-parole period imposed by the sentencing judge |
| Preventive detention | Eligible for parole at the end of the non-parole period imposed by the sentencing judge |
