Star Wars villain Darth Vader and a group of storm troopers spent some time washing cars ahead of Canada's Fan Expo, a massive convention of comic book, science fiction and horror enthusiasts.

The four-day convention drew 60,000 people last year, many arriving dressed as their favourite characters.

With time to kill ahead of this year's event, Vader and his troops cleaned cars at One A Minit Car Wash on Church Street on Wednesday.

Canadian Press photographer Aaron Vincent Elkaim documented the event and CBC.ca liked the photos so much we've compiled this photogallery.

Fan Expo runs from Aug. 25-28 at the Metro Toronto Convention Centre.
