I like how DT Dartmouth is evolving. Having grown up in the area, I recall, when Dartmouth was a separate city, that the downtown are had a nice vibe and was the place to go for shopping if you didn't want to cross the harbour. It was small, but along with Commercial St (Alderney Dr.) there were enough shops there, including a grocery store, that you could get pretty much anything you needed. The anchor store (the brick building on the corner of Portland and King Streets) was Woolworth's dept. store, and there were a number of other specialty-type shops along the street, like Jacobson's clothing store, Meyer's Sports Store, etc. It was a fairly vibrant area actually.
Of course a ferry ride would take you to the "big" stores in DT Halifax along Barrington and in Scotia Square if you were looking for something more specific.
With the shift to shopping centres, such as Dartmouth Shopping Centre in the 1950s (though the DT still seemed busy up to the mid 1970s) and Mic Mac Mall in the 1970s, the downtown started to go into a bit of a decline, but recently it's been great to see new smaller shops take over again. It's now a nice place to stroll around, stop in for a craft brew (or whatever your preference - in non-Covid times, of course) or browse some of the shops. With Kings Wharf, I can feel it revitalizing all over again, and it's a good thing.
I'm also anxious to see what the Canal St. area will look like in a few years time, once that development starts to take off.
