From Ken Niefer

I spoke to Kevin at Star Warning Systems regarding lens colours for snow removal vehicles. The latest info that he has from the MTO says that government or municipal plows will still be using blue lights. Private companies or individuals can use blue, but only if they are on private property (parking lots etc). If they have a blue light on while they are on the road they can be fined. They should have an amber light on their vehicle and then they will be safe in all areas. Apparently a lot of regional police departments are unclear as to what the law actually is.--
