@jordyndill, to get definitive answers to your questions about your patient and appointment status, you're best to contact Mayo Clinic International Services directly at:
Information Services Office in Canada
To speak with the patient advocate in Canada, please call:
807-701-5744
Or the International Appointment Office
888-441-2133

Here is further information specific for Canadians seeking care at Mayo Clinic

Since you have a Mayo patient ID, I agree with @johnbishop that you also have the additional option of getting efficient communication through the patient portal called Patient Online Services.
