CAT/C/CAN/CO/6 Oversight mechanism over security and intelligence operations 18. The Committee is concerned about the lack of information on measures taken by the State party to implement proposals made in the Policy Report from the Arar Inquiry for a model of comprehensive review and oversight of law enforcement and security agencies involved in national security activities (arts. 2, 12, 13 and 16). The Committee recommends that the State party: (a) Examine options for modernizing and strengthening national security review framework in a more timely and transparent manner; (b) Consider urgently implementing the model for oversight of agencies involved in national security agencies, proposed by the Arar Inquiry; and (c) Inform the Committee of changes made with regard to oversight mechanism over security and intelligence operations in the next periodic report. Detention conditions 19. While noting a Transformation Agenda launched by the Correctional Service of Canada with a view to improving its operations, the Committee remains concerned at (arts. 2, 11 and 16): (a) The inadequate infrastructure of detention facilities to deal with the rising and complex needs of prisoners, in particular those with mental illness; (b) Incidents of inter-prisoner violence and in-custody deaths resulting from high-risk lifestyles such as abuse of drugs and alcohol, which, as acknowledged by the delegation, still circulate in places of detention; and (c) The use of solitary confinement, in the forms of disciplinary and administrative segregation, often extensively prolonged, even for persons with mental illness. The State party should take all necessary measures to ensure that detention conditions in all places of deprivation of liberty are in conformity with the Standard Minimum Rules for the Treatment of Prisoners. It should, inter alia: (a) Strengthen its efforts to adopt effective measures to improve material conditions in prisons, reduce the current overcrowding, properly meet the basic needs of all persons deprived of their liberty and eliminate drugs; (b) Increase the capacity of treatment centres for prisoners with intermediate and acute mental health issues; (c) Limit the use of solitary confinement as a measure of last resort for as short a time as possible under strict supervision and with a possibility of judicial review; and (d) Abolish the use of solitary confinement for persons with serious or acute mental illness. Violence against women 20. While noting several measures taken by the federal and provincial governments to combat high violence against Aboriginal women and girls, including cases of murders and disappearances (CAT/C/CAN/Q/6/Add.1, paras. 76 ff), the Committee is concerned about ongoing reports that: (a) marginalized women, in particular Aboriginal women, experience disproportionately high levels of life-threatening forms of violence, spousal homicides and enforced disappearances; and (b) the State party failed to promptly and effectively investigate, prosecute and punish perpetrators or provide adequate protection for victims. 6
