1. Overview
1.1 Mandate
The Canadian Transportation Agency (CTA) is an independent regulator and quasi-judicial tribunal with the powers of a superior court reporting through the Minister of Transport to Parliament.
The Canada Transportation Act (the Act) is the CTA’s enabling legislation. The CTA has specific powers assigned to it under this Act:
- It is an economic regulator of modes of transportation under federal jurisdiction. It develops and applies ground rules that establish the rights and responsibilities of transportation service providers and their users, which level the playing field among competitors. These rules can be binding regulations, guidelines, or codes of practice;
- It is a tribunal that hears and resolves disputes like a court. It resolves disputes between transportation service providers and their clients or neighbours, using various tools from facilitation and mediation to arbitration and adjudication.
It has three key areas of responsibility:
- To help ensure that the national transportation system runs efficiently and smoothly in the interests of all Canadians: those who work and invest in it; the producers, shippers, travellers, and businesses who rely on it; and the communities where it operates.
- To provide consumer protection for air passengers.
- To protect the human rights of persons with disabilities to an accessible transportation network.

Appendix A
(Paragraph 11 – Applicable codes)
1.5 Independence and impartiality
Like other administrative agencies, the CTA is part of the executive branch of government and its purpose is to implement government policy. It has a duty to be independent and impartial to the extent determined by the laws voted by Parliament.
In its role as a regulator and regulations-maker, the CTA must sometimes engage with government officials, the industries it regulates, and consumer and disability rights organizations. Engagement also allows the CTA to stay informed and further its expertise in transportation matters, supporting its ability to competently advance its mandate.
Certain safeguards in the Act ensure the CTA is not controlled or inappropriately influenced by the government or others in its regulatory or any other role. The CTA has also adopted additional safeguards to maintain its independence and impartiality. Key safeguards include:
- rules regarding the selection, appointment, and tenure of members;
- conflict of interest prohibitions under the Act and other statutes;
- code of conduct and values and ethics requirements for members and employees, which are also embedded in various CTA practices;
- CTA rules, guidelines, and practices for complaint and determination cases, which ensure a fair process; and
- CTA engagement practices that include never discussing the merits of specific cases.
The CTA has an independence statement available on its website. It explains in detail the concepts of independence and impartiality, their place in common law and natural justice, and the safeguards that preserve them at the CTA. The statement also provides more information about the provisions in the Act, the government policies, and the court decisions that have informed the principles of independence and impartiality.
1.6 Values and ethics
Staff and Members at the CTA are bound by the Values and Ethics Code for the Public Sector. In addition, the CTA has two codes, one for staff and one for Members, which outline the values and behaviours the CTA expects its public servants to demonstrate as they carry out their professional duties.
Members
As Governor-in-Council appointees, Members follow a separate CTA code. The CTA Members Code of Conduct applies to all regular and temporary Members. It stresses that Members must always uphold the highest ethical standards, including in their interactions with staff and others and in their outside activities. The code explains in full the principles Members must apply when making decisions, which are, in brief:
- Impartiality
- Natural justice and fairness
- Preparation
- Timeliness
- Quality
- Consistency
- Respect for parties and participants
- (Maintaining appropriate) Case-related communications
Members should read their Code in conjunction with other, relevant ethical and conduct standards. This includes those set out in the Act or other legislation, policies, guidelines, other relevant codes, and their letter of appointment.
Staff
The Code of Values and Ethics for the Canadian Transportation Agency applies to every person employed by the CTA, including staff and managers, terms, casuals, students, and secondees. It sets out a connected set of principles that should be integrated into CTA actions, decisions, policies, processes, and systems. In brief, these are:
- Respect for democracy
- Respect for people
- Integrity
- Stewardship
- Excellence
As the Chair, you are responsible for overseeing the implementation of the Code, fostering a culture of value and ethics, and related activities. You are supported in this by the Executive Committee, which monitors the application of the Code, and by managers, who work to integrate the principles into organizational practices.
1.7 Evolution of CTA's mandate
Origins of the CTA
The CTA began as the Board of Railway Commissioners in 1904. The Board had the full powers of a superior court to hear all railway complaints, and its decisions were binding. It had regulatory powers over the construction, operation, and safety of railways (except those owned by the government), and set various freight rates and charges.
Key expansions of the mandate
The CTA mandate expanded at several key points during the twentieth century.
- 1938: The Board of Railway Commissioners became the Board of Transport Commissioners. In addition to rail powers, this board had new authorities over air and water transport, limited mainly to certain licensing and rates issues.
- 1967: The Board became the Canadian Transport Commission. It handled five modes of transportation – rail, air, water, motor vehicle, and commodity pipeline (except for oil products).
- 1988: Under the new National Transportation Act (1987), the Commission became the National Transportation Agency (NTA). The NTA served to implement a new National Transportation Policy enshrined in the Act (discussed in Section 3 of this binder) and had powers that included:
- granting transportation licences, reviewing public complaints, and helping resolve disputes between shippers and transportation firms;
- holding public hearings and settling disputes between shippers and carriers, but only in response to specific complaints or at the government’s request;
- providing mediation and final offer arbitration services on request; and
- monitoring major company mergers and acquisitions in all modes of transportation (a responsibility that is now largely with Transport Canada).
- 1992: The needs of travellers with disabilities became an integral part of the NTA’s jurisdiction, as the above Act was amended to include the words “accessible” and “persons with disabilities” in its declaratory clause.
- 1996: The new Canada Transportation Act renamed the National Transportation Agency as the Canadian Transportation Agency.
A twenty-first century agency
In this century, the National Transportation Policy has remained largely intact, and the CTA continues to implement it in its dual role as a quasi-judicial tribunal and an economic regulator. Responsibilities continue to include issuing licences to air and railway companies; resolving disputes over various air, rail and marine rate and service matters; and removing undue obstacles to the mobility of travellers with disabilities.
That said, additional key changes have further refined the CTA’s mandate, as follows.
- 2000: The CTA stopped setting maximum rates for moving Western grain by rail and introduced the Maximum Revenue Entitlement that continues to this day. Also in 2000, an Air Travel Complaints Commissioner position was created within the Agency to review and attempt to resolve complaints of airline customers.
- 2007: The CTA formally began using mediation to resolve complaints, having tested and proved it as a cost-effective, efficient alternative to the more formal and court-like adjudication process. However, the CTA mandate allowed it to resolve complaints with mediation on a case-by-case basis only.
- 2016: The CTA initiated a new approach to outreach and engagement, making industry stakeholders and travellers aware of their transportation-related rights and responsibilities, and how the CTA could help.
- 2017: Amendments to the Act empowered the CTA to, among other things, make new air passenger rights regulations.
- 2019: The CTA completed a three-year review and update of all its regulations and related guidelines. This resulted in key new regulations being registered that year, including the Air Passenger Protection Regulations (APPR) and Accessible Transportation for Persons with Disabilities Regulations (ATPDR). Various existing regulations were modernized through amendments (as discussed in Section 3).
- 2021: The ATPDR was amended, clarifying technical requirements.
- 2022: The APPR was amended, including to protect air passenger rights through the post-pandemic realities of travel.
- 2023: The CTA established a Complaints Resolution Office to address the backlog of air passenger complaints stemming from the above pandemic and post-pandemic developments.
