If you are looking for lessons, you should contact the Dalplex Rock Court. Check out their website:

Although no substitute for actual instruction and experience, you should pick up and read a copy of "Mountaineering: Freedom Of The Hills" 7th edition, available at MEC or the library. It is an invaluable resource for climbers and makes a great coffee table book. You can learn almost all the knots you will ever need in that book and get a grasp on some basic anchoring techniques.
Check out
http://www.climbnovascotia.ca for upcoming events and chances to get out and meet other climbers. Climbing with people more experienced than you (who know what they are doing) is also a good idea. Sorting out those who know from those who don't know what they don't know can be the tricky part.
