You will be required to submit your medical certificate to the Waterloo-Wellington Flgiht Centre no later than the end of August, prior to beginning your academic studies at Waterloo. Please note the process may take 2-3 weeks to complete and wait times vary to see the approved medical examiner. It is recommended that you initiate this as early as possible during the admissions cycle.
