Redacted diary reveals oil's hidden route to Harper

Redacted entries in Mike Duffy’s diary suggest he was in regular undisclosed contact with pipeline giant Enbridge during the height of the federal government's scorching attacks on environmental activists and charities in 2012.

The suspended senator’s journal shows a flurry of conversations and emails with or about top-level Enbridge executives, then PMO chief of staff Nigel Wright and the Prime Minister between January and June of 2012, just as the National Energy Board started its hearings on the Enbridge Northern Gateway pipeline proposal.

During this period, the federal government launched three parliamentary hearings, a senate inquiry and a major Canada Revenue Agency audit initiative focused on the activities of environmental charities, many of which opposed Northern Gateway.

None of the apparent contacts with Duffy were reported by Enbridge to the federal lobbyist registry, and Duffy's office redacted several key mentions of them.
