Nope... there's a whole series of photos on Flickr from last fall, when "X-Men: The Last Stand" was filming in downtown Vancouver. Apparently this sign was up for several days. One of the pictures is a closeup of the seal, which is a pretty plausible government department seal. You also get to see a shot of Angel in midair.
Fun to see photographic evidence, snapped by a random bystander, of the behind-the-scenes work that went into the movie!
