The Criminal Code categorizes two types of offences, Indictable and Summary Conviction. Hybrid offences (sometimes known as dual offences) are those which Crown can proceed with under either category. The decision will be based on the seriousness of the circumstances, when the offence occurred, whether or not the accused has been previously convicted of a similar offence and the likely sentence to be incurred. Once the Crown decides and advises the Court, the offence is treated as the kind the Crown has chosen. See Indictable Offence and Summary Conviction Offence.
