Internal nasal valve collapse. Do I book a consult or get my family MD to refer for OHIP coverage?

Hello, I've had a primary rhino and two revisions. I now have internal nasal valve collapse that is causing both a functional impairment as well as a defect to the visual aesthetic of my nose. Due to the functional nature, I think a procedure to fix it could be covered by OHIP, would I have to get a referral through a family MD or could I book directly to a plastic surgeon? I likely would need a graft from rib as my septum and ears have already been used up. Any Toronto area MD's out there?
