For the first 3 years (2006 through the start of 2009) it did.  Then it stabilized, then declined in the last 4 years.

At the end of the day the Federal government was almost the exact same size (relative to the economy as a whole) as it was when Harper started, with the exception of the military that shrank.

Overall the Federal government under the Conservatives saw the following:

- Own-spending excluding military saw minor increases
- Military spending saw big cuts
- Transfers to provinces saw big increases
- Transfers to individuals saw small increases
- Debt financing payments saw HUGE decreases

The last one is important because it is how the Federal government was able to deliver a small surplus in 2014/15 and 2015/16 despite fairly substantial tax cuts.
