This one's disappointing. Most of these old-school factories and warehouses (mainly textile) have been disappearing - there aren't many left. Randomly stumbled across this one in Yarmouth:
One of the only other remaining ones, in Windsor. 1/3 of the building is being preserved and redeveloped while the rest has been demolished by now:
Piercey's (independent hardware store in North End Halifax that got bought out by Rona) would have looked similar under all the grey paint; it was one of the only industrial buildings in that area to survive the Explosion:
Finally, what was left of a once-sprawling rope factory in Dartmouth; based on the first floor it would have been about as old as the Keith's Brewery or the oldest buildings at Dal:
On the bright side, the Shubenacadie Canal has been getting restored:
Note how long the canal was in operation
By the time it was completed, it was mostly obsolete, and during that 10 years it was used to build the rail line that replaced it and led to its closure. The canal itself took substantially longer than 10 years to build - multiple waves of immigrants over several decades. The "Marine Railway" was a section of the canal that carried boats over land on rails.
