Cogswell demolition buildings that could have been integrated into a historic district similar to old Quebec (from

Look how there was even a nice masonry building next to Morse's Teas that was torn down at some point then replaced decades later with a duller imitation historic facade:
Halifax even had and still has cobblestone streets. You can see an example in Granville Mall or around historic properties and there is another surviving example inside Scotia Square which was Buckingham Street before the redevelopment. Many other streets still have cobblestones that today are buried under asphalt, just like in those 1970's Quebec City photos.
