If there's no damage to the unit (dents, cracks, etc).... You can have Apple fix it at a flat rate. $325 or so US dollars (since I notice you're in Canada). Then you could use it or sell it.
The value working is probably around $700 at the most.
Broken you can probably get up to $300 for it.
Parted... probably... ($150 for LCD, $100 for various casing parts, $30 for combo drive, $15 for airport card, $30 for hard drive, etc, etc...) about $450 if you spent the time and effort to part it all out, and if you found buyers for everything.
Also, consider this... as a new or rare user here... and since you're from Canada... it might be hard to find buyers without going to ebay.
