Exhibit 14.1

CODE OF BUSINESS ETHICS

Policy:

AltaGas’ reputation of credibility, integrity and trust has been built on a foundation of operational excellence, continuous improvement, strong corporate values, high ethical standards, lawful conduct and corporate responsibility. Acting ethically, professionally and responsibly adds value for our stakeholders, including our shareholders, customers, employees and the communities where we live and operate.

Each director, officer and employee (collectively, “Employees”) of AltaGas Ltd. and its controlled subsidiaries, affiliates and operated entities in Canada, the United States and any other jurisdiction in which AltaGas does business or in which any such entities are located (collectively, “AltaGas”) represent AltaGas and are expected to act in a manner that will enhance AltaGas’ reputation for honesty, integrity and reliability. Our Code of Business Ethics (the “COBE”) is a statement of AltaGas’ business practices and how we do business. It reflects our commitment to a culture of honesty, integrity, and accountability. The COBE applies to every Employee of AltaGas and compliance is a condition of employment. Employees who fail to comply will be subject to disciplinary measures, up to and including termination of employment.

Contractors, consultants, representatives and agents must comply with AltaGas’ COBE and for the purposes hereof are included in the definition of Employee.

No code or policy can anticipate every situation that may arise. The COBE sets out fundamental principles to guide us and covers a wide range of business practices and procedures. It does not describe every circumstance that is subject to the COBE. Ultimately, personal judgment must be relied upon to determine the appropriate activities required to maintain personal and corporate integrity. The COBE provides an overall framework for the policies of AltaGas, but does not supersede the provisions of other policies of AltaGas or applicable law. When there is a conflict between the COBE and a written policy of AltaGas or applicable law, the written policy or law, respectively, will apply. If, after reviewing the COBE and the policies of AltaGas, you have questions, please seek additional guidance from your supervisor, management representative, or the Human Resources, Legal or Internal Audit department.

The following fundamental principles of appropriate business conduct have been established for all Employees working for or representing AltaGas:

Employees must ensure that no conflict exists between their personal interests and those of AltaGas.

If any Employee believes at any time that they may have created a situation of personal conflict, the conflict should be reported to their senior level designate.

Employees agree to hold all such information in confidence until its public disclosure by the owner of the confidential information, and shall access it only on a “need to know” basis, copy or reproduce it only as needed to perform work, return all such information in their possession upon demand and not disclose it or make it available to any other party without the prior written consent of the owner of the information.

Employees are obligated to promptly report any problems or concerns or any potential or actual violation of the COBE. The Employee’s first action should be to raise the problem with his or her supervisor.

Compliance with the COBE is a condition of employment for each Employee.

Although all Employees are responsible for ensuring prompt and consistent action against COBE violations, management and, in certain situations, the Board of Directors or its Committees are ultimately responsible for the investigation of and appropriate response to reports of suspected violations of the COBE.
