Canada is a member of the Open Government Partnership, and follows a two-year cycle running from July to June (2014-2016, 2016-2018 etc.) Included in the cycle is a mid-term assessment after the first year of the National Action Plan (NAP) and a final assessment after the second and final year. Assessment is composed of internal self-assessment and a third-party Independent Reporting Mechanism (IRM).
Canada has completed the first year of its second Action Plan (2014-2016) and so the internal self-assessment as of June 2015 is now available online. Feedback will be open online until Monday January 18, 2016.
The plan consists of a number of commitments, including Open Science. You can comment on the plan as a whole, or on individual commitments. You can also comment by sending an email to firstname.lastname@example.org
Based on the OGP calendar, the next Canadian National Action Plan (2016-2018) should be available in the July 2016 timeframe.
