Frequently Asked Questions

What are Emergency Wait Times?

Emergency wait times can be many things: the length of wait to be triaged, the length of wait to see a nurse, the wait to see a doctor or nurse practitioner and the wait until discharge home or to an inpatient floor. For the purpose of the information posted above, wait time refers to the length of time between being assessed by a triage nurse and seeing a doctor or nurse practitioner.

How will I be assessed for my turn to be seen?

The emergency department does not work on a first come, first served system. It’s important to know that critical patients will be seen first, whether they arrive on their own or via ambulance. Upon arrival in the department, you will be assessed using the Canadian Triage and Acuity Scale (CTAS). You will be seen by a doctor or nurse practitioners based on that assessment. In simple terms, the sickest patients will be seen most quickly.

How do you calculate Emergency Department wait times?

We measure the wait time posted above as the time from when you are assessed by a triage nurse until the time you see a doctor or nurse practitioner for assessment. Because new patients arrive frequently, estimated wait times can change significantly.

Your personal experience may vary from these posted wait times based on a number of factors:

  • Patients with more life-threatening situations arriving in the Emergency Department after you
  • Volume of patients waiting to be seen compared to the number of doctors or nurse practitioners working

Who updates the wait times on your website? How often is it refreshed?

The computer system that supports our wait times information is powered by Oculys®. Oculys’ web-based software takes historic and real-time data from our internal reporting systems and turns it into an understandable report, similar to the weather forecast. Just like the weather, it is important to understand that the data posted here represents the most current information about the chance or probability of waiting for a certain time. This automated system refreshes the data in real-time, ensuring the most accurate information available, and is what allows us to provide this information externally.
