That little neighbourhood in Dartmouth where the first shot was taken is kind of interesting. It was a part of the old town and developed in the early 1900's with small wooden houses. Around the 90's or so it was one of those places that really made the city feel small and less developed ("wooden shacks within view of skyscrapers", or at least highrises

) because what modern infill was built tended to be suburban style vinyl-clad split entries and the like. These days some of those have been torn down and replaced with custom 3-4 storey architect-designed houses with generous balconies and terraces and it has changed the feel a bit.
A similar phenomenon has been playing out in other areas like the Northwest Arm. It's a mix of in some cases national historic sites built for famous people worth millions of dollars, ugly and often pretty modest postwar suburban style houses that were built from about 1950-2010, and now modern mansions, many of which are starting to look pretty impressive. For better or worse, some of these properties seem to be treated like "international capital" in the same way many houses in Vancouver are.
The flip side of all this is a middle class family could afford some of these places back in the 90's, and higher earning professionals could afford even the most expensive areas, but that's no longer the case. Though Dartmouth remains comparatively affordable.
