- Independent shop hourly rates in Ottawa sit near the middle for Ontario, so labour is not unusually high or low here.

Questions drivers ask
Is a free code scan the same as a diagnostic?
No. A free code read at a parts store gives you a code, not a diagnosis. The code points to a system, not always to the part that failed. A diagnostic is the testing a technician does to find the actual cause.
Will the shop credit the diagnostic fee?
Some shops do if you have them do the repair, and some don't. Ask before you agree to the diagnostic. Get the answer on your written estimate so there is no surprise on the final invoice.
Can I drive with the check engine light on?
It depends on how the light behaves and how the car feels. A steady light with no other change is different from a flashing light or a car that runs rough. Check your owner's manual for what each warning means. If you are unsure, ask a shop to advise you before you keep driving.
