I think my preference would have been living arts drive.
As for why can’t other streets mimic confederation. I think the problem is that confederation is pretty much complete where as other streets like living arts has some empty spaces for condo sales centres or parking lots. Same with Duke of York. When those parking lots go im confident what’s happened at confederation will more or less continue. The thing is the closer you get to the mall though the more likely people just go to the mall. But I remain optimistic that once all the parking lots are done it will be significantly better.
