CF-CBI a McKinnon Enterprises G-21G serial 1203 was registered to J Pattison Ind. and then Crown Forest Industries, both on the BC coast and then to Walston Aircraft Parts & Leasing in Ontario from 1968-1991 according to the Transport Canada historical registration database.
I’m pretty sure I saw it on static display at the Namao Airshow in 1991 when Jimmy Pattison owned it.
There are 6 G-21As currently registered in Canada.
