Ramus Reconstruction, Right Madible. Please Suggest a Good Doctor in Canada?

Hi, I am new in Canada and been diagnosed with extremely large OKC in left mandible and requires recontructing the entire left jaw bone including the ramus. The doctors have open the gum for the cyst to shrink. After watching the cyst for 6 months they would see the size of cyst and the kind of reconstrcution required. Currently the doctors have suggested grafting by taking pieces from hip. Please suggest the best doctor or hospital in Canada for this case. Appreciate your help in this matter.
