The building's site is pretty crappy.
I may have the location wrong (the address is 5 hanna, right?) but, if not, the building is crammed up against the police garage on its east side. A derelict warehouse with a dirty parking lot and three superboards is to the south & west. True, there isn't a lot of traffic flow beyond the dozens of police vehicles however, that could easily change as this is roughly where the on and off Gardiner ramps for the Front Street extension were planned.
The Front Street extension is officially dead so there's no chance of the exit/entrance ramps happening.
