I was told that people could walk around in a junk yard and select what they want at very low prices. But I didn't meet one in Ottawa. What I mentioned here is a kind of business who collects collision cars and disassemble or classify all parts in computer system to sell. Once you contact one, they will ask your car's year, made, model and part, then check their system and give you an accurate answer: available or not, with price. So after a couple of phone calls, you could decide to buy from one of them, which will reserver that part for you. However, most of them are about 20-30KM far away from Ottawa Center. Good luck! (Definitely, the price in this kind of business is expensive than in junk yard, but less than 25% of a new part.)
