Elizabeth May may have resigned as the executive director of the Sierra Club of Canada to campaign for the leadership of the federal Green Party. But what you may not know is that her part-time contract with the non-partisan environmental group is continuing until the end of June. In an interview, the group's acting executive director Stephen Hazell confirmed Ms. May is still working for the Sierra Club on a number of projects, explaining "We're in a period of transition. And she does have a couple hats she's wearing." And Ms. May says "the amount of time I'm spending on Green Party activities (right now) is a very small proportion of my overall time" and separate from her work on those projects. "So the board has just asked that I avoid speaking publicly to the media on behalf of the Sierra Club." The reason: "We do not want to be seen to be favouring one political party or another," says Mr. Hazell. "We've got a Conservative government in Ottawa. And we want to try to work with these people. So, if we're seen to be Green Party acolytes, then that really diminishes our effectiveness."
