No worries, I don't always express myself as clearly as I'd like to.
I meant the structure noted on the photo below. I recall reading somewhere that it was intended to provide a covered route for rail passengers to get to the hotel above in typical Halifax weather. That said, I can't see a continuation of the shelter for crossing the street (which would turn to mud in wet conditions) to finish the journey to the King Edward Hotel, so it was probably only partially useful...
Here's a postcard on ebay that was colorized:

Apparently the hotel was rebuilt after the fire, BTW, survived the Halifax explosion and was torn down in the 1940s or 1950s...
