A/67/44 Degrading Treatment or Punishment (Istanbul Protocol) in such training programmes (art. 10). The State party should strengthen training programmes for law enforcement officials, military personnel and prison staff on the requirements of the Convention and assess the impact of such training programmes. The State party should ensure that relevant officials receive training on the use of the Istanbul Protocol to identify signs of torture and ill-treatment. (26) The Committee invites the State party to consider ratifying the other core United Nations human rights treaties to which it is not yet party, namely the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families, the Optional Protocol to the Convention on the Rights of Persons with Disabilities and the Optional Protocol to the International Covenant on Economic, Social and Cultural Rights.

(28) The State party is invited to update its common core document (HRI/CORE/1/Add.57), in accordance with the requirements of the common core document contained in the harmonized guidelines on reporting under the international human rights treaties (HRI/GEN.2/Rev.6).

(30) The State party is invited to submit its next report, which will be the fourth periodic report, by 1 June 2016. To that purpose, the Committee invites the State party to accept, by 1 June 2013, to report under its optional reporting procedure, consisting in the transmittal, by the Committee to the State party, of a list of issues prior to the submission of the periodic report. The State party’s response to this list of issues will constitute, under article 19 of the Convention, its next periodic report. 62. Canada (1) The Committee against Torture considered the sixth periodic report of Canada (CAT/C/CAN/6) at its 1076th and 1079th meetings, held on 21 and 22 May 2012 (CAT/C/SR.1076 and 1079), and adopted the following concluding observations at its 1087th and 1088th meetings (CAT/C/SR.1087 and 1088). A. Introduction (2) The Committee welcomes the submission of the sixth periodic report by the State party, which broadly comply with the guidelines on the form and content of periodic reports, but regrets that it was submitted three years late. (3) The Committee welcomes the open dialogue with the interministerial delegation of the State party and its efforts to provide comprehensive responses to issues raised by Committee members during the dialogue. The Committee further commends the State party for the detailed written replies to the list of issues, which was however submitted three months late, just before the dialogue. Such delay prevented the Committee from conducting a careful analysis of the information provided by the State party. GE.12-44492 115
