Canada holds a 54–46 advantage over Spain on the Relative Advantage Index.
The margin is driven by logistics & power projection (81% of the combined total, 460) and economic size (GDP) (57% of the combined total, $2.2tn). Spain leads on active personnel and military spending.
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side. Those factors are excluded and the remaining weights renormalised, never substituted.
