The newest development in the city right now are the extensions over at North and South Churchill called Small Island City. It's not on an island at all, but its adjacent to one.
There are about 8000 people living in these mixed use communities that were envisioned for people to be able to walk to work, eat, live and play in the same place. It's also home to a bustling transit station so people can get over to the side of the river for work via the subway.
