The registration period begins on the day the ex-offender relocates to Ontario.
The United States is the only country with a registry that is publicly accessible; all other countries in the English-speaking world have sex offender registries only accessible by law enforcement.
Three differing systems exist in determining offenders' inclusion in the registry: risk-based, sentence-length-based, and offense-based.
Unlike the federal registry which has an opt-out provision if an offender can convince a judge they are not a threat, the Ontario registry has no such provision.
As a result, individuals who have been convicted of a designated offence at any time after 2001, and relocate to Ontario, are obligated to register for a period of at least 10 years.
In offense-based systems, registration is required when a person is convicted under one of the listed offenses requiring registration.
Risk-based registries reflect the determined dangerousness of registered offenders, while sentence-length-based registries reflect the severity of the crime.
This scale is as follows: The New Zealand government has plans to introduce a sex offenders register by the end of 2014.
It will be managed by the New Zealand Police and information will be shared between the Police, Child, Youth and Family, the Department of Corrections, the Ministry of Social Development, and the Department of Building and Housing—government agencies which deal with child safety.
In the United States, the vast majority of the states are applying offense-based registries, leaving the actual risk level of the offender and severity of the offense uncertain. Studies has shown that actuarial risk assessment instruments consistently outperform the offense-based system mandated by federal law.
