Toronto buildings are undergoing a final polish and shine in anticipation of 2011 Doors Open Toronto event on May 28 and 29, 2011. New buildings open free to the public this year include Corus Quay, National Film Board Mediatheque, the Corkin Gallery at the Distillery District, Cannon Design, and Fire Stations 227 and 311, which will sure to be a hit with kids. The popular Citytv & OMNI Television – Rogers Studios, located just east of Yonge-Dundas Square, will be open for tours again this year (Sunday only). Be sure to get there early because the line-up for Citytv last year extended several blocks. If you haven’t seen the King Edward Hotel and its former Crystal Ballroom on the top floor, it’s worth a visit, particularly for the spectacular view of the city and Lake Ontario. The ballroom will soon undergo renovations so this may be the last year to see it in its original state. Around the corner, the narrow Gooderham Flatiron Building between Wellington and Front Streets always attracts crowds. You may also want to check out Fort York National Historic Site if you’ve never been. You will feel oblivious to your downtown surroundings as you become acquainted with Toronto’s early history during the Battle of York.
