The cheapest way is to go to a used car parts, buy a same one for your car. Replace it by yourself, or ask they replace it there or bring it to a garage to fix it.
Used car parts --- Do you have an Ottawa Yellow page at hand? Find Automobile Wrecking & Recycling, you'll find numbers these stores.
I know one, name of UNION, at 5402 Richmond Rd near Fallowfield Rd, Tel 1800-2633595 -- there has a lots of car parts, you could find your one! You can call them first.
