My dream for this is the main hall of the north building of the Telus convention centre. There were concerns about it being even more uneconomic as a convention centre after the BMO expansion was finished. When else do you get a large column free hall that has great loading dock facilities, utilities, and parking right on transit in the centre of the city. Could keep the east most bit configured as an eating area that could be locked off and used for chamber lunches and the dinners as needed if there were significant concerns.
