The CC-109 Cosmopolitan or "Cosmo" in RCAF service became the standard VIP aircraft as well as replacing the Douglas Dakota and the North American B-25 Mitchell in light transport duties.

With the close of production of the Convair CV-440 in San Diego, Canadair acquired the rights to the design along with the jigs, tooling and even three unsold 440s.

Instead, Canadair offered a series of CV-540 variants powered by Napier Eland turboprops.

After eight airframes had been re-engined, the company phased out further development work on the type, "orphaning" the remaining final two Eland examples, which were subsequently scrapped.
