Man Asking for Fathers Permission Before Proposing Marriage..

So I know tradiitons are more common in certain countries than others, I'm curious to know how many of you would ask for the brides fathers permission before proposing marriage? If you're married already, was permission asked before the proposal happened? Do you think it's necessary to do such a thing? Here in Canada, I would say this happens about 50% of the time based on what I've heard from others, I'm not engaged yet so I cannot shed light on my own personal experience. Thanks for commenting.
