How the dates are worked out
Under two years in total is served in a provincial jail. Parole eligibility comes at one-third of the sentence. The Ontario Parole Board does not grant day parole. Earned remission usually ends custody at two-thirds, though misconduct can push it later.
Two years or more is a federal penitentiary sentence. Full parole eligibility comes at one-third or seven years, whichever is sooner. Day parole comes six months before that, but never before six months in. Statutory release comes at two-thirds.
Concurrent and consecutive counts: concurrent counts run at the same time; a consecutive count starts when the one it follows ends. The dates run on the combined sentence.
Life for murder: full parole eligibility 25 years from arrest for first-degree murder, or the 10 to 25 years the judge set for second-degree; day parole three years before that. There is no statutory release.
Not covered here: a new sentence added to one already being served, intermittent (weekend) sentences and indeterminate sentences. The institution calculates those.
