Our story

A Shop Built on Straight Answers

Tune-Ups Inc has been fixing cars in Ontario one honest diagnosis at a time. Owner Mike built the shop's reputation the old fashioned way, by telling customers exactly what's wrong and what it actually costs to fix it.

Families keep coming back, and bringing their families with them. Parents, kids, and uncles all trust the same mechanic because the price he quotes is the price they pay, no surprise add-ons and no scare tactics.

From routine tune-ups to full engine replacements, we handle every car the way we'd want our own handled: carefully, honestly, and without wasting your time.

  • Honest, transparent pricing
  • Trusted across generations of local families
  • Everything from tune-ups to full engine replacements
  • Straight answers, no upselling

What customers say

“Mike is one of the last honest mechanics out there. I recommend this shop”

Daniel Macias

“The owner Mike is a great and honest man. He WILL NOT overcharge you! I walked out of there paying $320.00 for all new brakes, that is ALL I needed done! Been going there for years.”

Nutty

“Mike is the best and fairest mechanic I've met. I now have my daughter, mom, dad and uncle going to him. He's very honest and his prices are very reasonable. I'd refer him to anybody.”
