	Status: Approved

Employees (includes all officers and all full-time and part-time employees) of TransCanada Corporation and its wholly-owned subsidiaries, and operated entities in Canada, the United States and Mexico (the “Company”) represent the Company and are expected to act in a manner that will enhance the Company's reputation for honesty, integrity and reliability.  Our Code of Business Ethics (the “COBE”) is a statement on TransCanada’s Business Practices and on how we do business.  The COBE applies to all employees of TransCanada. All employees should be aware of all sections of the COBE and will be required to certify their understanding and agreement with the COBE in its entirety.

The COBE will not give answers for every situation.  Employees are encouraged to seek additional guidance if necessary.  If employees have any doubts about the right thing to do, they should ask their supervisor, manager or the Human Resources, Law, Transmission Compliance or Internal Audit Departments, as appropriate.   Employees can also call the Company’s anonymous Ethics Help-Line at

1-888-920-2042.

The following Fundamental Principles of appropriate business conduct have been established for all employees working for or representing the Company.  They are applicable in all countries in which the Company operates, unless the laws of those countries require a higher standard.

Our Values

Our four core values of integrity, collaboration, responsibility, and innovation, establish a framework for ethical and responsible behaviour in all that we do and they are the cornerstones of how TransCanada conducts business.  The values guide the way we work with each other, our customers, our business partners and other stakeholders.  We are all expected to strive to perform our work and make decisions in alignment with these values.  Details about the values are available on INFOcus.

Fundamental Principles

A.   Compliance with Laws

The Company will conduct its business in compliance with all laws, regulations and other legal requirements applicable wherever the Company is carrying on business.  No employee shall directly or indirectly give, offer or agree to give or offer a loan, reward, advantage or benefit of any kind to a foreign public official or to any person for the benefit of a foreign public official in contravention of the Corruption of Foreign Public Officials Act, Foreign Corrupt Practices Act, or other similar applicable law.

B.   Conflict of Interest

Employees must ensure that no conflict exists between their personal interests and those of the Company.  Employees should also avoid placing themselves in positions that may be perceived as conflicts.  Some examples of possible conflicts include:

·   Financial Interest - Employees and their families (families including spouse, children or spouse equivalent residing together) shall not own, control or direct a material financial interest (greater than 5%) in a supplier, contractor, competitor, or in any business enterprise which does or seeks to do business with the Company.

·   Outside Business Activities - Employees shall not engage in any outside business or activity that is detrimental to the Company.   Unless approved by the Company or your supervisor, employees are expected to spend their full time and attention performing their jobs during normal business hours or as contracted.

·   Outside Directorships - Employees shall not serve as a director, officer, partner, consultant or any other role in an unaffiliated organization including charitable organizations or non-profit foundations if that activity is detrimental to the Company.  Directorships in unaffiliated entities require the consent of the employee’s immediate supervisor, and of the Governance Committee of the Board of Directors in the case of the Chief Executive Officer and any member of the Executive Leadership Team.

The Internal Audit Department and the Ethics Help-Line have the primary responsibility for the investigation and/or the engaging of other investigative services for the Company.  If the investigation substantiates that fraudulent activities have occurred, the Internal Audit Department will issue reports to appropriate designated personnel and to the Board of Directors through the Audit Committee.  Employees who detect or suspect possible fraudulent activity of any officer, employee, vendor or any other party with any association with the Company, should report it immediately to the Internal Audit Department or the Ethics Help-Line.  Do not discuss instances of actual or suspected fraud with anyone except those authorized to investigate such conduct.

COMPLIANCE / EXCEPTIONS

Employees are expected to comply with all aspects of the COBE and to support others in doing so.  By certifying COBE, employees are also certifying that they are aware of, understand and are in compliance with all relevant and applicable Company policies and codes of conduct.  In the event that an employee violates the COBE, Company policies and procedures or any of the laws that govern the Company’s business, TransCanada will take immediate and appropriate action up to and including termination of employment, claims for reimbursement of losses or damages and reference to criminal authorities.  Please refer to the TransCanada Policies and ProceduresWeb Site for more information.

HOW TO RAISE A CONCERN

Employees are obligated to promptly report any problems or concerns or any potential or actual violation of the COBE.  The first action should be to raise the problem with your supervisor.  If that is not possible for some reason, or if taking it to your supervisor does not resolve the matter, it is your responsibility to take it up the chain of management within your organization or another department such as Human Resources, Law, Transmission Compliance or Internal Audit.  Employees can also call the anonymous Ethics Help-Line at 1-888-920-2042.   Callers do not have to reveal their identities.

TransCanada policy strictly prohibits reprisals or retaliation against anyone who files an ethics concern or complaint.  If you feel you have been subjected to retaliatory or disciplinary action because you have raised an ethics issue, call the Ethics Help-Line immediately.
