I work around the corner from the proposed Oakville location and I can confirm there is no action there yet. There is a large sign saying the lease for the space is still available, so I doubt any leases have been signed yet. I drive past that location daily on my way home from work, so I'll post updates if I see them beginning to break ground. :D
I can't wait! I've been to the Montreal location and have been eagerly waiting for them to come to Toronto since they first said they were thinking about it a few years ago. Here's hoping 2013 is a hard target, although I doubt they'll get this done for Spring. "Jump, and be free"
