If U have 2 wait over 4 hrs in pain & suffering to c a doctor, isn't this a violation of the Hippocratic oath?

In Ontario hospitals, unless you are fairly wealthy, you will have to wait at least 4 hours before a doctor will see you (this is when the waiting area is not crowded, late at night and it is not a weekend or a holiday or during a major emergency). Is this not unnecessary before assessment & treatment of shock & pain, and doesn't it violate the doctor's oath to "do no harm"?
