The old adage goes, 'It's the exception that makes the rule.' Sometimes the exception can be a little far-fetched but it is no less valid for validating the rule.
Based on Section 223 of the Criminal Code and the lack of any Canadian Law with regard to limits on abortion, it is theoretically possible for a woman to be pregnant with twins, for the woman to give birth to the first child (who is now fully protected by the Law as a human being) and then for the same doctor to abort/kill the second twin so long as he or she does so while the child's foot is still in the birth canal (even though the baby may be breathing and crying) and will face no legal consequences whatsoever. Like I say, a far-fetched scenario but valid according to Canadian Law.
