Raison d'être, mandate and role: who we are and what we do
Raison d'être
The Canadian Transportation Accident Investigation and Safety Board, commonly referred to as the Transportation Safety Board of Canada (TSB) in its day-to-day activities, is an independent agency created in 1990 by an Act of Parliament. It operates at arm's length from other government departments and agencies to ensure that there are no real or perceived conflicts of interest. The TSB's sole objective is to advance air, marine, pipeline and rail transportation safety.
The President of the King's Privy Council for Canada is the designated minister for the purposes of tabling the TSB's administrative reports in Parliament, such as the Departmental Plan and the Departmental Results Report. The TSB is part of the Privy Council portfolio of departments and agencies.
Mandate and role
The TSB's mandate—as described in the Canadian Transportation Accident Investigation and Safety Board Act which governs its work—is to advance safety in air, marine, pipeline and rail transportation by
- Conducting high-quality independent investigations into select transportation occurrences to identify the causes and contributing factors and the safety deficiencies evidenced by these occurrences;
- Making recommendations designed to eliminate or reduce such safety deficiencies;
- Reporting publicly on investigations and related findings in a timely manner; and
- Engaging with stakeholders to ensure that safety actions are taken to reduce risks and improve safety.

Operating context: conditions affecting our work
Operating context
The TSB operates within a vast and complex Canadian and international transportation system involving numerous organizations responsible for advancing transportation safety. While the TSB makes findings and recommendations to address safety deficiencies, it does not have the authority to compel their implementation. As a result, the Board must present its findings in a clear, persuasive manner that encourages action by stakeholders. This requires ongoing dialogue, information sharing, and strategic coordination with domestic partners such as Transport Canada, the Canadian Energy Regulator, and the Canadian Coast Guard, as well as with industry and foreign regulatory bodies.
With the continued globalization of the transportation sector, governments and industry are increasingly seeking to harmonize policies and practices to facilitate cross-border trade and the safe movement of people and goods. For example, rail operations that cross the Canada–United States border daily depend on harmonized rules to avoid operational delays and administrative burdens. This evolving context adds complexity to the TSB’s work: achieving safety outcomes now requires coordinated action by both Canadian and international stakeholders rather than engagement with domestic partners alone.
The volume and nature of the TSB’s activities are driven by the number, severity, and complexity of transportation occurrences, which cannot be reliably predicted. This inherent uncertainty presents challenges for resource planning and management. In recent years, the TSB’s visibility has also increased due to high-profile investigations, expanded outreach activities, and the growing use of digital and social media to share safety information. As a result, stakeholder and public expectations for timely, transparent, and impactful safety outcomes continue to rise.
