I have the amount that was saved in relation, so I have to do the math to figure out what the amount spent was. I believe, through a parliamentary question, the Department of National Defence answered this question and talked about money spent for retrofitting the military bases. It was already in their planned spending. They were already going to do that retrofitting anyway, and so that amount of money was already set aside for them to do that.
On June 9th, 2016. See this statement in context.
