Sure, the retail podium could be worse, but it must be better. It seems as though the people that designed this have never been to Yonge and were working off photos, because it's pretty obvious they don't have a solid grasp of what will work and what won't, what failures exist along Yonge and what is successful along Yonge. I mean, huge blank walls facing Yonge? Anyone who's ever actually walked or driven down Yonge will know that it doesn't meet the sidestreets at a right angle and so unless towers are flush together at an angle, they jut out fairly dramatically.
More than anything else, Yonge needs a simple, cohesive retail streetscape and this building does not help...it fills up space and gives nothing to the street. This complex will be replacing stores and restaurants (as well as a few properties with parking lots fronting Yonge). The first priority must be ensuring the replacement retail is as good as or better than what was demolished. The panel is right to note that recessed bits and blank walls aren't a good fit; having nothing a whole block of plate glass broken up by recessed voids and blank 'terra cotta' (precast) walls also isn't appealing. This type of facade often results in condo blocks with sterile streetscapes, where the retail spaces are differentiated by nothing other than a mingy little plastic panel above the door. It's the retail that will add life to this block, not the building itself. It's hard to say what kind of retail they're aiming for since the leasable area, the layouts, etc., aren't yet known.
Hopefully a community center or some similar institution (not likely as there is one right behind city hall about two blocks south) could find a home here. Though retail would definitely be better than private, residents' only space, it often lacks the vibrancy and animation that a community/socially-focused space can provide. Furthermore, the size of Yonge up here really makes it difficult for smaller, more 'independent' retailers to set up shop allowing larger, corporate stores (a la Shoppers, Hakim, etc.) to dominate the streetscape as they now do.
As Ed mentioned, the stretch of Yonge north of Empress is almost exclusively independent stores. I'd have trouble thinking of 11 chain stores/restaurants/banks on the entire 11 blocks between Empress and Finch. Centrium will be replacing 3 independent restaurants and 1 independent store, as well as one chain store and one instutition (a youth shelter that will move to a site on Canterbury) and one boarded up Speedy Muffler that closed a while ago. If Yonge north of Empress is not vibrant (it is busier south of Empress), the *only* reason is that the retail strip is fragmented. It's hard for many kinds of businesses to thrive on a strip where almost every block has one or more parking lots and where the retail is very discontinuous.
When the two service roads are finished, when Yonge closer to Finch has a tree- and flower-lined centre median, and when the area is more or less 'finished' (as Yonge is from Sheppard to Empress), the retail should be more successful and the strip will be more vibrant. It's going through a bit of an identity crisis right now...it's one of the most diverse neighbourhoods in the city and it's currently impossible for the retail strip north of Empress to specialize in anything or gain any real identity that would appeal to the entire city and boost foot traffic. Empress to Sheppard had a head start...give Empress to Finch another 10 years.
