The direction of recent and proposed justice policy in Canada is characterised by more criminal offences and longer periods of incarceration. This policy is based on the rationale that crime in Canada is increasing and the perception that Canadians are not safe. This article reviews whether there is empirical support for the rationale of this policy and the related assumption that this policy will reduce crime and better protect the public. From the existing literature, it seems clear that (1) crime is not on the increase in Canada, (2) it is unlikely that the reforms will lower crime rates, and (3) there is a large financial and human cost of the recent and proposed criminal justice policies. We conclude that "tough on crime" policies are not supported by the scientific literature (e.g., Smith, Goggin & Gendreau, 2002; Stalhlskopf, Males, & Macallier, 2010). Psychology would argue for evidenced-based justice policy; specifically, that early intervention, prevention, and rehabilitation are more beneficial in reducing crime in the long-term and more cost-effective (e.g., Aos, Phipps, Barnoski, & Lieb, 2001; CPPRG, 2010). Policy implications from the field of psychology are discussed.
