text: Hi, thanks for the response!
  
  I forgot to update this note after passing the site a few months back on Boulevard Rd. It was not open to the public, but I could determine that it is a convention centre. I've removed the landuse=retail tag and added an amenity=conference_centre tag, and done a bit more mapping in the area. If there are assorted shopping buildings built around the main building then they should be mapped separately and not the entire property mapped as retail. 
  
  As I believe this to be sorted out I'm resolving the note.
