Would like to fix breathing issues like deviated septum which is covered by OHIP but also under go Rhinoplasty at the same time?

My nose has been broken a few times, as well as completely split down the middle by a dog bite. I have trouble breathing and a decent scar on my nose already. I would like to correct breathing, reduce scaring and reduce a bump on my bridge. I would like to know how I can get most of this covered by OHIP and how much should I expect to pay for basic (if there is such a thing) Rhinoplasty at the same time? and should I see a ENT or a Plastic Surgeon?
