Sorry, Kanata Town Center is at Katimavik and Chimo. The bus station there is No.97. If you take he bus, just ask the driver to remind you when it arrives at Kanata Town Center.
Direction for driving from the east: Highway 407, take Castlefrank exit (just after March road), go south on Castlefrank and turn left onto Katimavik. It's on your left side. You'll see lots of bus stops and a Food Basic store.
