is a windshield necessary to pass inspection?

From what I understand (in Ontario) if you have a windshield you need wipers. If you don't have a windshield, obviously you don't need them. Pretty sure you don't need a windshield to Safety (obviously you would be removing it just to pass the test, which may be frowned upon by whoever is doing the inspection).
