The Days Inn on Carlton is becoming a new Holiday Inn. The doors are closed for now, but will reopen this fall.

Holiday Inn's site says this:

The Holiday Inn Toronto Dwtn Centre is now accepting reservations for arrivals after September 30, 2010.

With this hotel closed and with the Ritz-Carlton not ready, it's going to be tight for hotel rooms in Toronto during the G20 conference.
