Ontario Emissions Test
I suppose this is likely common knowledge for many car owners. From what I understand, there’s been a few changes to the emissions tests over the years and even quite recently. My question is, what does the most recent emissions test involve? Is it just a OBD reading from the on board computer or do they actually test the emissions from your exhaust pipe as well? What is the requirement to pass the current emissions test? For vehicles that fail the emissions test, is there some sort of grace to allow the vehicle to continue on the road?
