Canadian Defence Spending in Historical Context

I recently wrote a paper looking at Canadian defence spending in historical context.  The frame of the paper was to look at the Harper era, but I used it as an excuse to go all the way back to Sir John A.  I've included here an assortment of a few graphs and the main dataset, saved in Stata .dta format. Data comes from splicing Stats Canada's incomparable 'Historical Statistics' collection with a newer CANSIM series.  The dataset also includes PM and government party, by year.
