Sheikh Ahmad Kutty, A Senior Lecturer and an Islamic Scholar at the Islamic Institute of Toronto, Ontario, Canada , states,

A man can only marry only with the permission of the woman’s parents. If the parents are objecting for other than Islamic reasons, then she should find some other male relative of her or the local imams to represent her in marriage.
as for the man’s parents, he should try to have a free and frank discussion with them and make them aware of his intention to marry her. Marriage should not be a secret affair.
He should never marry without recourse to legal channels. He should only do it by following the procedures of the country.

May Allah guide all of us to what pleases Him!
