Study visits typically involve a lot of coordination of personnel, so it is very helpful to know ahead of time if you need to reschedule an appointment. We understand that even with the best intentions, there may be unforeseen circumstances. We really appreciate if you can give us advance notice when you cannot make your scheduled appointment, or you are going to be late. Please reach out to your study team directly. Email is typically the best way to reach most study teams, but if it's the morning of your appointment, you may also want to call our HNRU phone directly at 519-824-4120 x56314.
