If the relationship existed when Bill C-22 comes into force, those persons in relationships with people more than five years older than them will have a line of defense.
But if it's a marriage, and common law, if a couple was together for one year, or there was a child, and it existed and it met that definition when Bill C-22 comes into force, again, an exception will protect them.
In a short period of time, the 14-year-old or 15-year-old will become 16 years old. So the exception will cover them off to that point.
If the relationship forms after Bill C-22 comes into force, or if it doesn't meet the common-law definition--so they've lived together for less than a year and there's no child--it will be criminalized under Bill C-22. But on the point about whether there could be a permanent exception just to marriages and not also to common-law relationships, that would raise charter considerations.
