Emergency Response Systems Inc. (ERS) was a Canadian fire apparatus manufacturer located in Langley, British Columbia. ERS was founded in 1995 by two former employees of Anderson's Engineering. Intended as a higher-end apparatus builder, they built approximately 20 trucks for fire departments in British Columbia, including a few ULC-rated pumpers. Operations ceased around 2004 or 2005. ERS also served as the British Columbia dealer for Ambulance Demers.
