There are many types of sexual offences, which reflect the many ways in which people can come into sexual contact with each other. Offences include invitation to sexual touching; sexual exploitation; prostitution; sexual interference, voyeurism, corrupting morals, and child pornography. Sexual offences are considered by the police and the courts to be extremely serious and they attract some of the most severe penalties in the Criminal Code. A person convicted of a sex crime will be required to provide a sample of his DNA to the National DNA Databank, will be registered as a sex offender, and be unable to work, travel or live where he chooses except under strict limitations. This is in addition to a jail term and probation.
