Loss of rights due to criminal conviction refers to the practice in some countries of reducing the rights of individuals who have been convicted of a criminal offence. The restrictions are in addition to other penalties such as incarceration or fines. In addition to restrictions imposed directly upon conviction, there can also be collateral civil consequences resulting from a criminal conviction, but which are not imposed directly by the courts as a result of the conviction.
In Canada, criminal law is a federal matter, set out in the Criminal Code. Restrictions can be placed on certain activities following a conviction for a criminal offence. Four areas where there are restrictions are with respect to: (1) the use of weapons in the commission of a criminal offence; (2) driving a vehicle while impaired by alcohol or drugs; (3) electoral corruption offences.
When a person is convicted of an offence in which the person used a weapon, or threatened to use a weapon, the sentencing court has the power to prohibit the person from possessing a weapon for a certain period of time. In the case of certain offences, the prohibition on possession is mandatory. In other cases, the court has discretion whether to impose a prohibition on possession.
For first offences, the court can set the prohibition period as any time up to ten years. For subsequent offences, the convicted person is prohibited from possessing a weapon for life. However, even for first offences, the court can impose a lifetime prohibition if the convicted person used a weapon against the convicted person's intimate partner, the convicted person's children, or any person living with the convicted person. As well, there is a lifetime prohibition on possessing prohibited firearms or weapons (such as fully automatic firearms), and restricted firearms (such as handguns).
The Criminal Code contains several offences related to driving a motor vehicle, including driving while impaired or with a blood alcohol count greater than eighty milligrams of alcohol in one hundred millilitres of blood (".08"), impaired or .08 driving causing bodily harm or death, dangerous driving (including dangerous driving causing bodily harm or death), and street racing. A person convicted of one of these offences can be subject to a prohibition on driving a motor vehicle for a certain period of time.
For convictions for impaired driving or driving over .08, the court must impose a mandatory driving prohibition of at least one year and not more than three years for a first offence. The length of the mandatory driving prohibitions increase with second and subsequent offences. If the convicted person participates in an interlock program, the length of the prohibition may be reduced, but must be at least three months. Similar mandatory prohibition orders are imposed for offences involving a motor vehicle which cause bodily harm or death and for street racing.
