Urban Search and Rescue (USAR) is a general term for a group of specialized rescue skills that are integrated into a team with resources that include search, medical and structural assessment capacity. Heavy USAR (HUSAR) Task Forces locate trapped persons in collapsed structures and other entrapments using specially trained dogs and electronic search equipment. The Task Forces breach, shore, lift and remove structural components, use heavy construction equipment and various other techniques to remove debris, and medically treat and transfer victims.

Toronto HUSAR is an acronym for Heavy Urban Search And Rescue Team, which is a multi-service, multi-skilled, and multi-functional task force developed within the framework of existing response agencies such as the Toronto Police Service/Paramedic Services/Toronto Fire Service.
