Here are some houses along the Northwest Arm in Halifax. If you wanted to tour the city's nicer houses, you'd be best off doing it by boat. There are some nice historical ones like Sandford Fleming's mansion which is on a private street.
These properties seem more and more to be like high-end homes in Vancouver; the builders and the buyers come from all over the place, and the prices are sometimes out of proportion with average properties (average lot will be $200,000-500,000 then a prime lot is $2M). I don't know what the story is behind these twins.

Note that these are not like those houses in the lower part of the aerial on the last page. You can buy a small house in that area for under $300,000.
