After delivery to CP Air July 3, 1979, C-GCPO carried on through mergers to Canadian Airlines, Air Canada and finally in the original group of 737s transferred to Zip Air in September 2002. Withdrawn as Zip was absorbed back into Air Canada in September 2004, the aircraft was returned to Polaris Leasing, who owned it by this time and stored at Mojave, CA in October. Finally leased to Aero Condor Peru from November 2006 to February 2009 then returning to storage.

When photographed, this 737 was nearing the end of it's time in Canada. Delivered to CP Air October 1, 1982, it would wear Canadian Airlines, Air Canada, Tango and Zip colors through mergers. It was stored at Mojave, CA in October 2004 after Zip was wound up by Air Canada in September. The aircraft was re-activated and sold to Venezolana Airlines as YV287T in February 2007.

On final for 9R.

Delivered October 30, 1981, C-GCPY was another 737 that would last throughout the mergers of the '80s and 90s and would end service with Air Canada in 2003. It was sold to Triton Lease and returned for a short lease with Zip Air from April to August 2003. Triton leased it out again to Merpati Nusantara Airlines as PK-MBS from 2004 through 2008.

Delivered to CP Air May 22, 1979, this 737 would remain in Canada through mergers with Pacific Western Airlines (Canadian Airlines) and Air Canada. Eventually placed with Air Canada's low fare Zip Air, the aircraft was sold to Pegasus Aviation in April 2003.

Acquired from Air Canada after the phase out of Zip Air, this 737 would fly with Canadian North until stored at Edmonton, AB in 2015. The registration was cancelled February 7, 2017.

In 2000, Air Canada took over operations of Canadian Airlines and merged the airlines in 2001. To standardize the fleet, Canadian's DC-10s were disposed of quickly and the 737s went a couple of years later. C-GKCP is photographed in short term storage but would be re-activated for Air Canada's low fair Zip Air. When Zip was shut down, this 737 went to Canadian North.

The Empress of Watson Lake was delivered to CP Air November 1, 1982.

Former Canadian Airlines 737s received full Air Canada (or Zip Airlines) colors before the fleet was disposed of, this one in 2003.

Canadian Airlines introduced this new color scheme in January 1999. In December 1999, the airline would be acquired by Air Canada and the scheme quickly disapeared.

Transferred from Air Canada's fleet for the last year of Zip Air's operation, this 737 subsequently was sold to Canadian North.

Delivered to CP Air April 20, 1981 and worked after mergers with Canadian Airlines, Air Canada and Zip. Sold to Wells Fargo Bank January 2004, it was placed with Nova Air in Mexico (XA-OCI) the following December.
