Skywalk Closure (2011-2013)
In July 2011, construction begins on the Ripley's Aquarium of Canada to be built at the base of the CN Tower. For the period of July 2011 to July 2013, the construction crew must close the western entrance/exit of SkyWalk, the pedestrian connection between the CN Tower/Rogers Centre and Union Station, the TTC and GO Transit. Access between these two areas is still possible and facilitated by a signed detour.
Here is the detour info:
