(1) after the offender has served one third of the additional sentence, commencing on the day on which the additional sentence is imposed, if it is to be served consecutively and is imposed under the Criminal Code (Revised Statutes of Canada, 1985, chapter C-46) or another federal statute; or
(2) after the offender has served one third of a single sentence determined pursuant to section 33, in other cases.
However, conditional release cannot resume if the parole board or a person designated in writing by the parole board has ordered a suspension pursuant to section 161.
