If we use # of Costco as an indicatin of consumer-power, Great Toronoto Area (GTA) has 9 Costco and 4 T&T (almost 2:1). Then Ottawa for sure can sustain 1 or 2 T&T, since we have 3 Costco.
I hope the hunt club/riverside area, (which already home to so many expensive houses) can attract few upscale Chinese restaurants after T&T is buildt. Almost like old Toronto China town v.s. now Hwy 7?
Just dreaming
