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