How do you get records from a Doctor Who has died?

A patient has the right to their records although there is a fee (at least in Canada) but it's minimal. Since your doctor died, then either there is another physician that took his place and they would have your records or, the doctor's office would usually tell you of another doctor to see and when you do they will automatically pass your records to them. If there is another doctor that took the place of your doctor and you don't care to be treated by him/her you can request your medical records be released. They will make you sign a document of release.
