Where is Brampton Wilderness Centre/Siemans?

It says in the Recreation Guide that it's in 2719 Bovaird Dr. But when I searched it in google, there's no building that says "Siemens/BWC." Can someone please tell me where this place is cause this is the place where I'm going this Wednesday for my Nature Photography 101 class. And until now I still can't find where this place is. Please? :(
