PartSource was launched by Canadian Tire in 1999 to be the biggest and best auto parts specialty chain in Canada. Now it has 13 stores in Alberta, 6 in Saskatchewan, 5 in Manitoba, 58 in Ontario and a bunch of information on their website. If you go into any one of their stores, PartSource offers a few handy and free services. If you need a tool for your car, you can loan one for free from their Parts Pro as long as you put down a deposit. They also have free electrical testing for any alternators, starters, ignition modules, or batteries that you bring in. And if you need some guidance, diagrams, or schematics for your vehicle, they've got free Shopkey 5 terminals that you can print information and diagrams from. Not bad for free!
