What is the difference between Code 3 and Code 4 in Ontario policing terminology?

• A. Code 3 is an emergency response with lights and sirens; Code 4 means scene secure or no further assistance needed.
• B. Code 3 is a security alert; Code 4 is a medical call.
• C. Code 3 means pursuit; Code 4 means arrest.
• D. Code 3 is for weather alerts; Code 4 is for fire.

Answer: (A)

Code 3 is an emergency response: officers use lights and sirens to get to a scene as quickly as possible, prioritizing the call and treating it as urgent. Code 4 is when the situation is under control and the scene is secure, meaning no further assistance is needed and units can wind down or return to normal duties. This distinction matters for coordinating resources and maintaining safety—Code 3 signals high priority and potential risks on the way to the scene, while Code 4 signals that the immediate incident is resolved and normal operations can resume.
