I believe that Canadian-marked B-47 was on special loan from the US, and was the only one we ever had in Canada.
Designated the CL-52, it was the only foreign-operated B-47 ever. Apparently the airframe was twisted out of shape by the big Orenda Iroquois, and it was scrapped on its return to the US. It was reportedly a terrible dog to fly with all that extra weight way out back.
