EXPERTISE IN MOTION
What Our Car Mechanical Services Include
01
Engine Repair & Diagnostics
A misfiring engine or a check-engine light should never be ignored, especially on Toronto’s congested commuter routes. Our technicians use advanced automotive diagnostics equipment to read fault codes, inspect spark plugs, ignition coils, fuel injectors, and the ECU, then carry out targeted engine repair that restores performance and fuel efficiency. Drivers from Scarborough to North York trust us to find the root cause, not just clear the code.
02
Transmission Service
Your transmission takes constant punishment in stop-and-go traffic along highways like the 401 and the DVP. We service the full drivetrain: fluid flushes, filter replacements, solenoid inspections, and complete transmission rebuilds when necessary. Catching transmission wear early prevents far costlier repairs that result from delayed servicing.
03
Suspension & Steering
Ontario’s freeze-thaw cycles create the potholes that knock suspension components out of alignment season after season. We inspect and replace control arms, ball joints, tie rods, wheel bearings, and struts to restore stable handling and a smooth ride. Residents in Brampton, Mississauga, and North York frequently bring us vehicles with suspension damage caused by exactly these road conditions.
04
Exhaust System
A damaged catalytic converter, failing oxygen sensor, or corroded exhaust pipe affects both your vehicle’s performance and its ability to pass Ontario’s emissions requirements. We repair and replace mufflers, exhaust pipes, and catalytic converters, keeping your vehicle compliant and running cleanly. Exhaust corrosion is especially common in Ontario due to road salt exposure during winter.
05
Electrical Systems
Modern vehicles rely on complex electrical systems, from the alternator and starter motor to body control modules and driver-assistance sensors. Our technicians diagnose short circuits, faulty wiring, failing alternators, and battery charging issues with precision. If your dash warning lights won’t clear or your vehicle won’t start reliably, our electrical diagnostics will find the fault.
06
Cooling System
An overheated engine causes some of the most expensive damage a vehicle can suffer. We service radiators, water pumps, thermostats, and coolant hoses to keep your engine at the correct operating temperature year-round, critical during both Markham’s humid summers and the deep cold snaps that hit the GTA each winter.

Areas We Serve
Tire Choice Auto Centre serves drivers across the Greater Toronto Area from our North York location at O’Connor Dr. We regularly assist customers from Toronto, Scarborough, East York, Etobicoke, Mississauga, Brampton, Markham, Vaughan, Richmond Hill, Hamilton, Pickering, and Ajax.

FREQUENTLY ASKED QUESTIONS
Costs vary widely depending on the type of repair. A diagnostic scan typically runs $80–$150, while larger jobs like transmission service or suspension work can range from $150 to $600 or more. Tire Choice Auto Centre provides written quotes before any work starts so there are never unexpected charges on your bill.
Straightforward services like a cooling system flush or spark plug replacement often take one to two hours. More involved work, such as a transmission service, engine repair, or full suspension overhaul, may require one to two full days. Our team will give you an honest time estimate when you book, and we’ll communicate any changes if additional issues are found during the inspection.
Yes, a pre-purchase mechanical inspection is strongly recommended before buying any used vehicle in Ontario. A technician can assess the engine, transmission, drivetrain, braking system, and suspension, identifying issues that aren’t visible during a test drive. This can save you thousands of dollars in unexpected repairs after purchase.
Ontario’s harsh winters and pothole-heavy spring roads create specific wear patterns. Suspension components, including control arms, ball joints, and wheel bearings, are frequently damaged by potholes. Cooling systems need regular attention due to extreme temperature swings. Exhaust systems corrode faster from road salt, and electrical systems are stressed by cold starts. Preventive maintenance before and after winter is essential for any GTA driver.
If your check-engine light is on, your vehicle is misfiring, stalling, losing power, or showing unusual fuel consumption, those are signs that engine diagnostics are needed rather than routine maintenance. Routine maintenance follows a mileage or time schedule. Diagnostics are triggered by specific symptoms or fault codes. Either way, our North York team can assess and advise you accurately.
It depends on the fault. A solid check-engine light often signals a non-urgent issue, such as a faulty oxygen sensor, that should be addressed soon but typically allows short-term driving. A flashing check-engine light usually indicates a serious problem, such as engine misfiring that can damage the catalytic converter, and means you should stop driving and arrange an inspection immediately. When in doubt, call our North York shop and describe what you’re experiencing.
