This claim is only true if Canadian military spending were to increase if the United States decreased its military spending and if such increase in Canadian military spending came at the expense of its healthcare spending. Do you have evidence that this is the case? In the 90s there was a downsizing of the U.S. military. Did Canada correspondingly increase it's military spending? I don't know but I doubt it.
Given that the U.S. healthcare system ranks behind many countries with public healthcare and that the U.S. spends way more as a percent of GDP on healthcare than any other country it's quite reasonable to believe that taxpayer healthcare is as good as paid healthcare after taxes and is cheaper.
