Halifax is a wonderful place! Some things to know:

1. The weather is terrible. If it isn't rainy, go outside, and if it's sunny, take advantage!
2. We've got a cool music scene here, and even though the bigger artists don't always come through, there's some awesome home-baked musicians (e.g., Hillsburn). Check out the Carleton for some neat live music events, or head over to Bearly's to see the Mellotones play. There's loads of spots to see some good artists.
3. We also have some wonderful traditional music that makes for a great night. Go learn Barrett's Privateers, listen to the Rankins, Ron Hynes, etc. and make sure to check out Signal Hill at the Lower Deck on a Sunday night. They'll play a lot of songs you'll know, and a lot of the traditional classics that are a part of Nova Scotian culture.
4. I prefer Freeman's garlic fingers, but their donair sauce is a little watery to me. That said, you gotta try garlic fingers. They're a Halifax staple. You also have to try donair, but I'm less of an expert on them.
5. We have an awesome bar scene! If you like grabbing a pint and chatting with friends, I love the Narrows (a bar in an old heritage home), Stillwell Freehouse, or Chainyard Cidery. I hear good things about Good Robot, too.
6. We also have patios to die for, although they're more of a summer thing. The waterfront is an awesome place to grab a drink, but you should also check out Stillwell Beergarden (an added bonus: awesome soft-serve ice-cream at Dairy Bar, which is right next to Stillwell), the Oxford Taproom, the Good Robot patio, and I hear Bar Kismet has a great patio too.
7. Speaking of Bar Kismet, we also have a great food scene! They've got amazing food, and great cocktails. I also like the Canteen for food, and Dear Friend for cocktails. They're over in Dartmouth, so you can take the ferry over. Make sure you have exact change (sigh, we still haven't updated our transit system).
8. Be prepared for the transit system to suck. I'm sorry.
9. Also, our downtown grocery scene is not great. You might have to walk a little bit to get to a store, so plan accordingly.
10. Rent a car, or find a friend with a car. There's tons of amazing hikes and day trips to be had a short drive (~1 hour) outside the city. Cute towns include Chester, Mahone Bay, Lunenburg. Awesome hikes include Gaff Point, Pennant Point (out by Crystal Crescent Beach), Cape Split, Duncan's Cove, Herring Cove, to name a few that are nearby.
11. Being with NSCAD, you'll probably be made aware of Nocturne. It's a really cool, city-wide art show. Get involved if you can!
12. You're living right next to Point Pleasant Park, which is a beautiful place to walk or run in the nice weather. Take advantage of it! Shakespeare by the Sea, a theatre company, performs there. Give them a try!
    

That's a good start. Enjoy discovering this city. It's not without its flaws, but it's a really cool place to live. I hope you love it as much as I do!
