Let me begin by saying that the question typically is: why is Infrastructure Canada's spending decreased since the end of the 2007 Building Canada fund? When you look at the 2013-14 main estimates they show that our authorities were about $3.9 billion in voted appropriations. In 2014 our voted appropriations dropped to $1.3 billion, and in 2015-16 we plan to spend about $1.6 billion. I'm assuming that's the question you're trying to get at. The explanation behind the decrease is that it's not a program cut in itself.
