I see one of the proposals wanted to build a glass ceiling all over that part of Rideau Street.. Would've been really nice if it would have been done right. Like the Gallerie Vittorio Emanuele in Milan, It. Main issue here would have been to do it right and still leave it open at both ends because closing it would just make it a "mall". But leaving it open would provide light and nice warm breeze during the summer while still protecting people from the snow and elements during winter...
