About diagnostic imaging in Mississauga

What to bring to your appointment

When arriving at an imaging clinic in Mississauga, bring your Ontario health card and your physician’s referral form (requisition). Most clinics require an original signed requisition. If you received a digital requisition from your provider, print it or call the clinic to confirm they accept digital copies.

Certain exams require preparation — fasting for abdominal ultrasounds, a full bladder for pelvic ultrasounds, and so on. Your ordering provider or the clinic will give you specific instructions when you book.
