Interpretation Note

Wait times have been impacted by reduced service delivery during the COVID-19 pandemic. Under the Chief Medical Officer of Health’s Directive #2 and Memorandum, from March 19 to May 26, 2020, health service providers and health service organizations including hospitals were directed to reduce elective surgeries and other non-emergency clinical activities to preserve capacity during the pandemic.

Time to Patient's First Surgical Appointment

This is how long patients waited from a surgeon, specialist or central intake centre receiving the referral from the patient's doctor for a surgery or procedure - other than pediatric, cancer, cardiac, orthopedic or eye surgery - to the patient's first surgical or specialist appointment.

Patients with emergency conditions (Priority 1) are seen immediately. They are not included in wait times data shown here. Patients' priorities are assigned by their surgeons. The wait time is displayed for the larger health organization to which a hospital belongs. Even if a procedure is not offered at a selected hospital, data will appear for the larger health organization.
