Our story
About Ontario Auto Repair
We're a family-run shop in the heart of Ontario, run by Lalo and his son. Customers walk in not knowing what's wrong with their car and walk out with a clear, honest answer, because that's how we've always done business.
We take the time to explain every repair before we start, and we back it up with fair pricing. Whether it's a full diagnostic, a transmission issue, or an AC that needs to blow cold again before the weekend, we get it done right.
Many of our customers have been with us for years, and they send their family and friends our way. That kind of trust is earned one honest repair at a time.
- Family-run, two generations
- Clear explanations before any work starts
- Fair, upfront pricing
- Trusted by loyal, repeat customers
