The technical briefing is designed to feature specialized units from the Toronto Police Service, Peel Regional Police, the OPP, the RCMP and the Canadian Forces that will be utilized during the G20. It will provide an opportunity for the media to become familiar with what they will see on the streets of Toronto during the summit from a law enforcement and security perspective. Units on display include Police Dog Services, Mounted Unit, Marine Unit, Public Safety Unit, Traffic Services, Video Services, Emergency Task Force and Tactical Emergency Services from both Toronto EMS and Toronto Fire Services.
