This report outlines Enbridge Inc.’s economic, environmental and social impact on the communities where we do business. The theme of our report this year is ‘Our Community Partners’, which reflects our commitment to working with the communities where we do business to ensure a sustainable future.

This report can be viewed as disclosure of our corporate responsibility performance. Our intent is to share information in a standardized way on issues that are most relevant to our internal and external stakeholders. Our transparency efforts and our commitment to reporting are not limited to this document. We see value in different methods of reporting and communicating, and this report complements our annual report to our shareholders and our website where we disclose our financial performance.

Reporting conventions

Most of this report refers to year-end 2005 data. Where noted, we have included selected 2006 updates. Where you see the words Enbridge Inc. or Enbridge, we are referring to the whole company and its subsidiaries. Dollar figures are in Canadian dollars, unless otherwise specified.

Dialogue

At Enbridge, we look at a number of sources to give us feedback on our corporate social responsibility report. We do this so we can continually improve our report and our reporting process.

Enbridge’s Employee CSR Advisory Committee – a cross-functional group of senior staff who provide advice on CSR policies and strategies – has reviewed drafts of this report and given much valuable input. As well, the company’s Corporate Disclosure Committee has reviewed drafts of this report and provided useful feedback. We also review the results of our annual employee survey before preparing our CSR report to ensure we are capturing feedback from our own employees.

And we look at a number of external sources including our annual customer surveys that are done by Enbridge Gas Distribution and Liquids Pipelines to measure customer satisfaction and identify ways we can better meet our customers’ needs.

External CSR Advisory Group

In 2006, for the first time, Enbridge assembled an external CSR advisory group to provide independent feedback on our corporate social responsibility report. This six-person advisory group consisted of individuals from a variety of organizations who were familiar with Enbridge and knowledgeable on a range of CSR issues faced by Enbridge. Advisory group members participated in a one-day workshop and a follow-up conference call, and provided detailed input on how we could improve our report. Participants brought their individual perspectives and expertise and did not represent their organizations. Stratos Inc. facilitated the advisory group. Participation by advisory group members does not represent an endorsement of this report.

Enbridge found the sessions very useful and learned from advisory group feedback, making changes to the draft version of this report to address improvements suggested by the advisory group. Enbridge was not able to address all of the suggestions from the group but will incorporate much of their feedback into future reports.

GRI Guidelines

We have prepared this report in a way that meets the “in accordance” specifications set forth by the Global Reporting Initiative’s 2002 Sustainability Reporting Guidelines.

The GRI offers a comprehensive framework for reporting a company’s impacts and activities. A GRI index can help readers match this report with sections of the GRI (for more information, visit www.globalreporting.org). We strongly support the GRI as a core tool for corporate social responsibility reporting because it has credibility with a broad cross-section of stakeholder groups. We are committed to using the GRI Guidelines, and we support efforts to advance reporting on the basis of the GRI. (See the Assurance Statement page for more information.)
