The brook is called Halls creek (maybe hull's?). It's chalk full of trouties if you go further up the stream (you can also catch it off the transcanada). If you hit it just right you could get some nice sea trout running through there. Since the opening of the bridge there seems to be a lot more movement in all the little rivers and streams that feed into the petty.
It's best to fish this river above the "mudline" so i'd suggest getting it either on the road behind that (I think it's called university ave) or catch it on the transcanada and follow the trail until you get to the quary and start there.
