Country 94 has a brief story talking about how to fill vacancies in the uptown. Link: http://country94news.blogspot.ca/2013/02/big-box-retailers-could-also-help-fill.html
The article indicates that councillor Donna Reardon is pondering how the city could attract big-box brands (perhaps things like Best Buy, Winners, etc.) to put smaller stores in the city centre when running mega-size suburban shops. The article suggests this practice may be in place in some European cities.
