Assessment process

The National Assessment Process is led by Natural Resources Canada, and we depend on the collaboration of a broad partnership of subject-matter experts and assessment users from all orders of government, Indigenous organizations, universities, professional and non-governmental groups, and the private sector. The public is also involved through meetings, conferences and online engagement tools. An advisory committee provides the Process with ongoing advice and input. Together, we follow these steps:

  1. Launch: We engage broadly to discuss the scope and goals of an upcoming assessment
  2. Plan: We plan the assessment’s products (i.e., outcomes) and adjust the approach to best meet our goals
  3. Build author teams: We invite subject matter experts to lead chapters and form writing teams that represent a range of expertise and regions in Canada
  4. Assess: These teams gather, analyze and assess information, then draft assessment chapters
  1. Review and scientific editing: Experts review the drafts for accuracy and completeness
  2. Finalize: Author teams work with the Assessment Secretariat to finalize the content
  3. Release: We translate, design and distribute the assessment products

Our team

The National Assessment reports are made possible through a team of experts who lead and support the assessment process and accurately convey their findings.

  • The Assessment Secretariat is housed within the Climate Change Impacts and Adaptation Division (CCIAD) of Natural Resources Canada. They work with the advisory committee to coordinate the logistical aspects of the assessment process, conduct scientific editing, contract support services, and produce the final reports.
  • The Advisory Committee is comprised of subject-matter experts spanning government, academic institutions, Indigenous organizations, non-governmental organizations and industry nationwide. They provide advice and input on issues such as assessment approach and goals, report organization, supporting products, who else to involve, and communicating the process and results.
  • Lead authors oversee the delivery of their reports or chapters, ensuring that the writing teams contain the appropriate expertise and adhere to format and writing guidelines. They are responsible for responding to reviewers’ comments.
