Inspection Station

Our friendly, certified licensed mechanics are ready to provide you with exceptional professionalism. Our service centre is a Motor Vehicle Inspection Station and we are able to provide you with a Safety Standards Certificate valid anywhere in the province of Ontario.

Safety Standards Certificate

Our prices for providing a safety certification are lower than industry standards! Our safety inspections are done with the utmost care, attention and professionalism at the most affordable price.

Bang for the Buck

Our exceptionally low rates do not exclude our exceptional service – we do not compromise the quality of our work at the expense of our prices. While most auto repair shops charge anywhere from $100 to $110 per hour labour rates - their prices are no competition.

Brake Job Replacement


From the brake pedal to hydraulic brake fluid, brake master cylinder to power brake booster, drum brakes to disc brakes and electronic anti-lock brake sensors, Boss Auto Service technicians know every part of your brake system inside and out and can perform brake repair on any make and model. Schedule your next brake service or brake job today!

Oshawa Oil Change


Oil is the lifeblood of your engine. It reduces friction, lessens wear, provides lubrication, forms a seal between the pistons, rings and cylinder walls while helping to cool engine parts. Without the cleaning action of new oil, carbon and varnish buildup would be toxic to the engine. And engine oil even dampens the shock and noise of moving parts. Schedule your next oil change today!

Tire Change Oshawa


Tires provide the traction for stopping, cornering and they help absorb road bumps to give you a smooth, safe and comfortable ride. Schedule your next new tire change or used tire purchase today!

Exhaust Muffler Oshawa


Your vehicles exhaust system – exhaust pipe, catalytic converter, extension pipe, muffler, connecting pipe, resonator, tail pipe, clamps, flanges, gaskets and hangers – reduces noise and conducts dangerous engine gases to the rear of the vehicle. To ensure your personal safety and vehicle performance, be sure your exhaust system is in good working condition. Schedule your next muffler change or exhaust system repair today!

Tune-Up Oshawa

Engine & Tune-ups

Infrequent tune-ups can lead to poor fuel mileage, rough running and difficult starting. Learn when to schedule an engine diagnostic test to determine your tune-up needs, whether it’s a fuel injector service to restore engine performance, power and mileage or fuel filter and air filter replacements. Schedule your next vehicle tune-up or engine overhaul today!

AC Top Up Oshawa

Heating & Cooling

The temperature under the hood of your vehicle is vitally important. Maintaining the right temperature may require a quick part replacement, or it could involve more complex repairs. Our technicians can perform a detailed inspection of your vehicle’s heating and cooling systems to determine what work is needed. Schedule your next AC top up or radiator and heating system repair today!

Suspension Repair Oshawa

Steering & Suspension

Your vehicle’s steering and suspension is responsible for providing optimal ride comfort and handling performance. Because normal road conditions can cause the shocks, struts, and springs of your suspension system to weaken over time, these worn suspension parts may reduce vehicle stability and driver control. They may also accelerate tire wear. Schedule your next strut replacement or suspension repair today!

Transmission Repair Oshawa


The transmission in your vehicle is a very important component that allows the gear ratios to change as you drive, if you are driving an automatic transmission car. There are vehicles with manual transmission as well, where you would have to either shift down or up when needed. If you do not take in your vehicle for the needed transmission repair in Oshawa, you could potentially have to deal with an expensive repair in the long-run. Our Oshawa auto repair technicians specialize in transmissions! Schedule your transmission rebuild or transmission replacement today!

Car Battery Replacement Oshawa

Batteries & Electrical

The electrical system of your vehicle consists of several components, with the major ones being the battery, starter and alternator. Other components, such as wiring, relays, fuses and connectors help direct the power where it needs to go. The battery is one of the most important parts of your vehicle – without its power to start the engine, you’re not going anywhere. Your vehicle battery wears out, just like anything else. Temperature extremes in either the summer or winter can shorten a battery’s life, as can repeatedly draining your battery completely. Schedule your next car battery replacement or electrical repair today!

I’ve never felt more comfortable in dealing with an Oshawa auto repair shop. I trust them in what they inform me on, and what their recommendations and I never feel like I am being taken for a ride, especially with their rates.
Chris, from Whitby
Left my vehicle in the morning before work, and I picked up my vehicle by lunch. I really can’t ask for better service. The work was done quick, and it was done right. Thank you gentlemen, it was a pleasure.
