When it comes to pushing the proposed Northern Gateway pipeline, Stephen Harper’s Conservatives are campaigning almost as hard as they do during an election. That’s a credit to D’Arcy Levesque, Enbridge’s vice-president of public and government affairs, and someone Maclean’s tabbed as one of the 25 most important people in Ottawa. That honour is all the more impressive given that Levesque doesn’t even live in Ottawa, but instead makes his home in Calgary. Levesque, whose career straddles the intersection of politics and pipelines in Alberta (he’s a former advisor to ministers in Alberta’s provincial Tory government and a longstanding energy industry insider), has influence that extends beyond that, too. He’s played a big role in fostering a supportive relationship between corporate Canada and the arts, and in delivering Enbridge’s sponsorship of big ticket events like the Governor General’s Performing Arts Awards.
