Transportation Safety Board of Canada Regulations

Understanding the new TSB Regulations and how they affect your work in the pipeline industry

What's new in the new regulations? The Transportation Safety Board Regulations were changed for the first time since 1992, bringing them up-to-date with the current transportation industry and legislation. As of 12 March 2014, Part 2 of the Regulations came into effect. Part 1 comes into effect on 1 July 2014. This fact sheet highlights some important changes that may affect your work in the pipeline industry.

The new regulations make it easier for you to report pipeline occurrences without increasing costs or the administrative burden

What has changed?

The TSB has put in place new regulations that repeal and replace the previous version. The new regulations are simpler and better aligned with other federal legislation, industry standards and international agreements. This has changed some of what you must report to the TSB in the event of a transportation occurrence and how we investigate. In particular, the new regulations:

  • Make it easier to understand what needs to be reported;
  • Clarify basic rules pertaining to witness interviews; and
  • Bring certain definitions and terminologies up-to-date.

Who do the regulations apply to?

The new regulations apply to all pipelines occurrences in Canada within the legislative authority of Parliament (i.e. federally-regulated pipelines). They also apply to any occurrence outside Canada if the TSB is investigating.

Compliance with the new regulations is mandatory. Companies that don't comply can be held accountable under the Canadian Transportation Accident Investigation and Safety Board Act.
