Wrongo! BBD acquired the CL-600 design from Crown-corporation Canadair before BBD acquired Lear. The 600 design was produced for about 8 years by Canadair, then by BBD before Lear was acquired by BBD. in fact, the Lear family sued BBD for royalties that were part of Canadair’s deal when they bought the design rights from Bill Lear. The issue ripened when BBD built the CRJ and the Lear family wanted to be paid royalties as a derivative design. BBD, in Canadian court lost and settled for a large sum, which has never gone down well with either side.
The Learstar 600 was actually a smaller diameter fuselage than the final CL-600 due to freighter design for FDX. The CL-300 series is closer to the Lear 600 fuse.
