The A321 entered service with Air Canada with the delivery of Fin # 451 in November 2001. The aircraft is the largest of the Airbus A320 family and has been deployed on domestic and transborder routes that warranted higher capacity than the A319 or A320 giving the company a lot of flexibility of scheduling.
Fins 452 to 460 were delivered through to September 2002. Fins 465, 466 and 467 were leased from 2002 until 2005 but the fleet remained mostly stable at 10 aircraft until 2015 when Fins 461 to 464 and 473 were acquired after serving in the Air France fleet.
Five more aircraft have been acquired for the Rouge brand. This is the only Rouge fleet where new aircraft have been ordered. Fins 468 to 472 were delivered between November 2015 and May 2016 and are being deployed mainly on sun destinations.
