At least as far as the government of Canada is concerned you'd better. If you can manage to keep track of that much detailed and insignificant information you are certainly capable of tracking the path of a billion bucks. To claim one cares more about shoe sizes than that which extends and improves our life is complete and utter nonsense. Canadians have this vision of government as a warm, nurturing, overweight woman suckling them at her breast. In reality government is neither a woman nor nurturing.
Government is people.
Which brings me back to the problem of the lost funds. One billion dollars is a lot of money. Moreover, it's a lot of taxpayer's money. Actually, it would be more if you really think about it. Those who don't earn an income would not be eligible to sue.
