I'm having a great deal of difficulty imagining Markham approving this with the current parking ratio. This is not a particularly walkable neighbourhood -- the nearest grocery stores are the better part of a kilometre away via vast expanses of stroad and parking lots. The proximity to the GO station means, at best, that some households will be able to get by with one car instead of the more customary two or three. The 0.5 parking spaces per unit proposed seems to be awfully... aspirational about the area's level of car independence.
Hell, knowing Markham, residents will want to drive their cars across the street to the GO parking lot to catch the train.
