It's really too bad they've committed (without an extensive cost/benefit analysis, apparently) to buy 65 F-35As @ $125MM+ each when they could have had a fairly seamless transition to F-18E/Fs @ $50MM+ each plus the cost of engines. I love the Canucks, but they're never going to go to downtown Beijing or Vladivostok anyway - not that an F-18E/F w/ jamming support couldn't do it anyway.
I think it has more to do with a 'keeping up with the Jones'" than anything else. Canada's two closest partners, the U.S. and U.K., are both buying the JSF; why should they settle for 'second best'? If they want to be seen as a front line military, then they need to have top-of-the-line equipment.
Besides, why would any service advocate for buying an older technology when they can ask for the shiny, new gucci-gear???
It's not like fiscal prudence has ever entered into the equation when discussing the acquisition strategies of either the U.S. Navy or Air Force...
