Adam, two words: Real Estate.
By the way, Zellers and Canadian Tire are not new entrants to this site. They have been at Centre Mall since at least 1993. Only as smaller incarnations.
And anyone who does not think the surrounding commercial areas will see a pick-up in occupancy, you are practising in self-denial. People who used to shop at Centre Mall before the redevelopment shopped at Zellers and Canadian Tire. After the redevelopment, they will continue to shop at Zellers and Canadian Tire. The redevelopment will offer the first new grocery store in central Hamilton (outside of a No Frills) in over 20 years, and the only truly decent one to be found anywhere between Dundurn, the lakeshore, the escarpment and Centennial. Demographics of weekly visitors to the site will increase as a result, resulting in an increase in activity in the entire area. And here's a news flash, with Zellers and Canadian Tire as the anchors, the core demographics of the new redevelopment will remain practically the same as its previous incarnation.
Yes, Zellers and Canadian Tire offer mostly minimum wage jobs. But that was all that was here before the redevelopment, so how has the site worsened? By creating even more minimum wage jobs here? In actuality, the grocery store will bring many jobs with wage rates double that of minimum wage, so your arguement doesn't really pan out here at all.
I am curious, what retail concept could have been here that would have created jobs that were not principally minimum wage?
