On the unbuilt projects side, Canadair licenced the N-32 Raider with plans to build a Canadian version as their CL-3. Canadair test pilot, Alexander Lilly, went to Northrop and flew the YC-125 in 1949. Later that year, the Canadair designation was changed to CL-12.
It's not clear whether the CL-12 designation change was made to cover local changes. As a rule, Canadair designations were not changed between civil and military types (such changes were covered by sub-type designations). It is possible that the CL-3 designation covered Canadair's YC-125A equivalent while CL-12 covered a proposed YC-125B variant for arctic operations.
Canadair customer inquiries seem to receive no positive responses. Makes me wonder if an N-23 re-engineered for only two engines might have done better on the bush side of the civil market?
