Rachel McAdams has still got it. Even though Canada’s starlet has been flying under the radar, she still caused quite the stir when she slipped into the Waterkeeper Gala on Tuesday night. Held at Palais Royale in Toronto, Gord Downie shared his water story to kick off an energetic performance with The Sadies. The list of notables was endless, from Peter Mansbridge and Edward Burtynsky to Atom Egoyan and Leslie Feist. All of the performers shared an idea, a memory, or a belief about water while they told stories, laughed, and in some cases even sang. The evening drew to a close with a live art auction that raised more than $500,000 to support Lake Ontario Waterkeeper’s work on water issues. parties@globeandmail.com
