The Bombardier CRJ700, CRJ900, and CRJ1000 are regional airliners manufactured by Bombardier and based on the CRJ200. Final assembly of the aircraft is at Montréal-Mirabel International Airport in Mirabel, Quebec, outside Montreal, Quebec, Canada.

Following the success of the CRJ100/200 series, Bombardier Aerospace produced larger variants in order to compete with larger regional aircraft such as the Fokker 70/Fokker 100 or the BAe 146 family, and competed later with the Embraer E-Jet family. It accounts for over 20% of all jet departures in North America and globally the family operates more than 200,000 flights per month : a CRJ takes off every 10 seconds.

Design work on the CRJ700 by Bombardier started in 1995 and the programme was officially launched in January 1997. The CRJ700 is a stretched 70-seat derivative of the CRJ200. Seating ranges from 63 to 78 for the CRJ700 versions, however. The CRJ700 features a new wing with leading edge slats and a stretched and slightly widened fuselage, with a lowered floor.

The early build aircraft were equipped with two General Electric CF34-8C1 engines. However, later build aircraft are now equipped standard with the -8C5 model, which is essentially an uprated 8C1. Most airlines have replaced the older engines with the newer model, while a few have kept the older -8C1 in their fleet. Maximum speed is Mach 0.85 (895 km/hr, 556 mi/hr) at a maximum altitude of 12,500 m (41,000 ft). Depending upon payload, the CRJ700 can travel up to 3,620 km (2,250 mi) with original engines, and a new variant with CF34-8C5 engines will be able to travel up to 4,660 km (2,900 mi).
