Vancouver Public Space Network has posted up the competiotion brief for "Where is the square?" a couple of weeks ago. The brief and a few other supporting files are on their
website.
The best parts of this competition are the absolute freedom in locating "the square" - as long as it is in Vancouver proper - and that the entry is open to anyone who wants a go at it.
The entry forms are due on January 30th and the designs are due on March 20th.
