A bit of a bugger that the F-35A cannot refuel from the RCAF's tankers though..... Whereas the -B and/or -C could. The Lockheed snake oil salesmen would no doubt charge a fortune to fit a 'CF-35A' with a probe rather than a hole.
That said, I gather that the RCAF are very impressed by the Rafale. Which would surely meet their northern needs.
