"The Optional Protocol establishes two procedures aimed at strengthening the implementation and monitoring of the Convention. The first is a complaint procedure that allows individuals and groups to bring petitions to the Committee on the Rights of Persons with Disabilities if they believe their rights under the Convention have been violated. The second is an inquiry procedure that allows the Committee to inquire into allegations of grave or systematic violations of the Convention by a State Party. The Optional Protocol was adopted by the UN in 2006 and entered into force in 2008. As of November 2017, there are 92 States Parties to the Optional Protocol. On November 30, the Government of Canada tabled the Optional Protocol in the House of Commons. Tabling in Parliament is an important and necessary next step in the federal process toward accession of a treaty, such as the Optional Protocol, and allows Parliament to review and discuss it before a decision is taken on accession. The Government of Canada continues to work with the provinces and territories, which must undertake their own internal processes prior to providing their feedback on accession."
