It's an excellent question. In the recent budget, $440 million was invested in the agency over five years to increase our ability to tackle tax evasion and tax avoidance. We are committed to returning to the government, to the crown, $2.6 billion in revenue. That's the proposition.
Sir, your question about return on investment is an excellent one. Within the agency this is a key factor in where we mobilize our audit activity and resources. We calculate that, and insofar as there is a diminishing rate of return, it's probably not an area for greater activity.
