Pipeline recommendations

The Transportation Safety Board of Canada (TSB) is responsible for advancing transportation safety. One of the ways it does this is by making recommendations to federal departments and other organizations to eliminate or reduce safety deficiencies.

Under our Act, federal ministers must formally respond to TSB recommendations and explain how they have addressed or will address the safety deficiencies. The Board evaluates the responses and their overall effectiveness, assessing them as Fully Satisfactory, Satisfactory Intent, Satisfactory in Part or Unsatisfactory, and assigning them a status of Active, Dormant, or Closed (see the definitions in the Assessment Rating Guide). Progress made to address TSB recommendations is assessed by the Board on an ongoing basis.

Responses to recommendations assessed to be Fully Satisfactory are assigned Closed status. Before 2014, the term Inactive was used instead of Closed. Although the index below has been changed to reflect the use of the new terminology, the underlying reassessment documents may not have been.

For recommendations and assessments made before 1 January 2005, please refer to our annual reports.
