I don't know why we need such strict height restrictions either...
Housing costs (prices/rents) are high and continuously increase due to demand and not enough building starts. The area is central, served by LRT, bus routes, parkways, near retail, office and many amenities. If it doesn't interfere with Parliament sightlines, why have these 20, 30, 40 floor limits? Why couldn't this area house a 50 or 60fl story tower? Let the market dictate the height.
Meanwhile.. this 55fl tower is being proposed/built in Kitchener.
