Wow they're really packing them in for a suburb. I guess York Region is serious about getting their money's worth on their share of the subway costs. Also FYI, that subway station will be ~200m west of Jane & Hwy7 at Millway.
34 and 35 storeys is way too short. These buildings would look great if they added at least another 20 floors to each tower otherwise they are going to look like the NY Towers stumps.
In the next 20 years Vaughan will increase urban boundries just 3% while adding 68% to population. 45% of the growth will occur in "Intensification Areas" on 4% of the land and 40% of the municipality will be protected greenspace.
