Canada holds a 61–39 advantage over Mexico on the Relative Advantage Index, a clear margin.
The margin is driven by military spending (73% of the combined total, $37.5bn) and logistics & power projection (84% of the combined total, 460). Mexico leads on active personnel.
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
