Exhibit 99.1

	Code of Business Conduct & Ethics

This Code of Business Conduct & Ethics reflects Cenovus’s commitment to conducting our business ethically and legally while we pursue progressive and innovative approaches to developing energy resources.  At Cenovus, we can be trusted to do what we say.  We are a company that conducts its business with respect.  This Code will be used to identify and manage ethical situations and to provide guidance in making ethical business decisions so that our staff can fulfill these commitments.

Compliance with Laws and Regulations

As employees, contractors and directors, we comply with the laws, rules and regulations of Canada, the United States and any other countries in which Cenovus operates.  We comply with the requirements of applicable securities regulatory authorities and stock exchanges.

Corporate Opportunities

Our employees, contractors and directors are prohibited from taking opportunities, using Cenovus property or information or their position with Cenovus for personal gain or competing with Cenovus, based on information discovered through the use of corporate property, information or position.

Conflicts of Interest

Our employees, contractors and directors avoid situations where personal interests could conflict, or appear to conflict, with duties and responsibilities or the interests of Cenovus. A conflict of interest may occur where involvement in any activity, with or without the involvement of a related party, prevents the proper performance of employee, contractor and director duties for Cenovus, or creates, or appears to create, a situation where judgment or ability to act in the best interests of Cenovus is affected.

When faced with an actual or potential conflict of interest, our employees follow the procedures outlined in the Conflict of Interest Practice and contractors review and follow the provisions of their written contracts.  Our officers and directors follow obligations that are set out in relevant statutes and company by-laws and inform the Chair of the Board of Directors of any such conflict. Our commitment is to ensure that employees and contractors are not involved in any decision or operation related to a conflict and that officers or directors are not involved in any decision or operation related to a conflict.  This is the commitment of our employees, our Executive Team and our Board of Directors.

Fraud and other Similar Irregularities

At Cenovus, we are committed to protecting the revenue, property, information and other assets of the company and our shareholders from any attempt, either by the public, contractors, agents or our own employees, to gain financial or other benefit by deceit.

- 2 -

We have zero-tolerance for fraudulent activities and fully investigate any suspected acts of fraud, misappropriation or other similar irregularity. Cenovus will pursue every reasonable effort, including court-ordered restitution, to obtain recovery of Cenovus’s losses from the offender or other appropriate sources.

Any employee or contractor who has knowledge of an occurrence of fraud, or has reason to suspect that a fraud has occurred, must immediately notify their supervisor or company contact or may report their suspicions in accordance with the Investigations Practice.

Confidentiality and Disclosure

Confidential information includes all non-public information that might be of use to competitors, or harmful to Cenovus or its customers, if disclosed. Confidential information must not be disclosed unless specific authorization is given to do so or such disclosure is legally mandated. Knowledge of confidential information about another company gained in the course of work duties at Cenovus must be protected in the same manner as confidential information about Cenovus.

Employees, contractors and directors must not speak on behalf of Cenovus unless authorized to do so and should refer to the Policy on Disclosure, Confidentiality and Employee Trading.

Taking advantage of, or benefiting from, information obtained at work that is not available to the public is not permitted. Friends, relatives and associates must not benefit from such information. Where insider information is known and not yet publicly disclosed, employees, contractors and directors must avoid acquiring or disposing of any business interest, including publicly traded securities, whether directly or through another person.

If an employee or contractor is not sure whether information has been publicly disclosed, they should consult with a member of Cenovus’s Legal group for guidance before engaging in any transaction in any securities of Cenovus. Officers and directors should consult on such matters with the persons listed in the Restricted Trading and Insider Guidelines for guidance before engaging in any transaction in any Cenovus securities. All securities transactions are subject to the Policy on Disclosure, Confidentiality and Employee Trading and if applicable, the Restricted Trading and Insider Guidelines.

These confidentiality obligations remain in effect even beyond termination of employment, service agreements or Board of Directors appointments with Cenovus or its affiliates.

Inducements and Gifts

At Cenovus, we do not accept or give gifts, favours, personal advantages, services payments, loans, or benefits of any kind, other than those of nominal value that can be made as a generally accepted business practice. The Acceptance of Gifts Guideline provides further guidance regarding gift-giving and receiving and should be referred to and or written approval from Cenovus leaders should be requested. Gift-giving practices may vary among different cultures, and therefore local gift practices and guidelines will be considered when addressing these issues.

We do not tolerate soliciting, accepting, or paying bribes or other illicit payments for any purpose. Situations must be avoided where judgment might be influenced by, or appears to be influenced by such unlawful or unethical behavior. Payment or acceptance of any “kickbacks” from a contractor or other external party is prohibited.

Examples of laws to which Cenovus is subject and abides by include the Corruption of Foreign Public Officials Act (Canada), the Foreign Corrupt Practices Act (U.S.A.) and equivalent legislation in other countries. Non-compliance could have serious ramifications.

While Cenovus does not normally support the use of facilitating payments, in some jurisdictions where it is determined to be absolutely necessary for the conduct of Cenovus’s business, the foregoing Acts allow such payments to be made if not prohibited by local law and only upon approval by the appropriate Executive Vice-President and upon consultation with and approval of internal legal counsel.

Political Activities

Cenovus does not participate in improper intervention in political processes and does not make financial contributions or contributions in kind (e.g. properties, materials or services) to political parties, committees or their representatives, unless permitted by law, and approved in advance by Cenovus’s Vice-President, Government Affairs and Corporate Responsibility, as delegated by the President & Chief Executive Officer and Executive Vice-President, Communications & Stakeholder Relations.  All contributions will be reported annually to the Board of Directors. In such situations, we fully comply with legal requirements for public disclosure.

At Cenovus, our employees, contractors and directors may choose to become involved in political activities as long as they undertake these activities on their own behalf and may, on a personal level, give to any political party or candidate.  Reimbursement by the company is prohibited.

Lobbying Activities

We comply with the Lobbying Act (Canada) and the Lobbyist Act (Alberta) which impose reporting requirements on lobbying communications with certain officers and employees of the Government of Canada or the Government of Alberta (known as “Public Office Holders”  or “POHs”). Employees do not have communications with a POH unless they have been registered by Cenovus under the Lobbying Act (Canada) or the Lobbyist Act (Alberta), except where otherwise permitted by the applicable legislation.

The accuracy of asset and liability records must be maintained by comparing the records to the existing assets and liabilities at reasonable intervals, and taking appropriate action with respect to any differences.

All business transactions that employees, contractors and directors have participated in must be properly authorized, properly recorded and supported by accurate documentation in reasonable detail.

Cenovus is required to provide full, fair, accurate, timely and understandable disclosure in reports and documents that are filed with, or submitted to, the U.S. Securities and Exchange Commission, the Alberta Securities Commission and other Canadian securities regulatory authorities, the Toronto Stock Exchange and the New York Stock Exchange, as well as in other public communications made by Cenovus.
