CL-215. It never was a de Havilland Canada product and was designed and manufactured by Canadair in Montreal, funded by the province of Québec.
Both deHavilland Canada, and Canadair were purchased by Bombardier, which resulted in some inter company cooperation at that point. The CL415 powerplant installation has some commonality with the Dash 8. When the Viking company group purchased the propeller powered products from Bombardier, they did not buy the jet products. Thus, the CL415 line sort of merged with the deHavilland product line, which makes good sense to me.
