I have been coming here every two years since moving to Ontario in 2020. The price is fair and the service is great. The owner is helpful and professional. The wait time for walk ins is also surprisingly quick. I will keep giving them my business!

Pulled up to Ontario Smog and had a really easy experience. It’s a small shop but they move quick. The guy working there was straightforward and got my car done faster than I expected. No hassle at all. Thank you, highly recommended.
