Rosey Toes will always inspect the bike
throughly before giving you the safety paper. And he will join in passionately when you complain that the tires are bald because those lazy Canada Post bastards did not deliver your new tires yet. He will swear and laugh and everyone will have a good time.
There are tons of things that could be wrong and unsafe with a bike that passes safety, even if it's done fully by the book. The safety is just a (mostly) meaningless piece of paper required by the Ministry. Actually taking care of the bike's mechanics is another thing entirely.
