If you are coming to Halifax and you want a different view of the Halifax side, you can take the ferry to the Dartmouth side of the harbour.
The ferry costs $2.50 per person, you can get a transfer and then come back over to the Halifax side. I will tell you that there are plenty of things to do in downtown Dartmouth as well.
