With respect to the government's choosing tax to provide social policies, the role of the department and public servants is to do the best possible analysis we can do and put the pros and cons of using different tools before ministers to make those decisions. So based on the principles of the tax system and the pros and cons of different measures within the tax system, we put that before ministers and they choose how they want to proceed.
There are measures that are more conducive to using the tax system, and there are measures that aren't conducive to using the tax system as a tool. For example, if you're going to income-test something, if as a policy objective ministers choose that they're going to provide the Canada child tax benefit but it's only going to be to lower-income individuals, then a natural tool to use in that respect would be the tax system because you're already measuring income automatically. If you've already got the tax system in place and it measures income, you don't want to create an entire new administration or bureaucracy to provide funding to individuals for that, and so you're able to provide, for example, the child tax benefit.
So those are some of the considerations we put before ministers in determining what tools are best to use in providing these kinds of measures. So as for advice on a particular measure, I can't reveal the advice we would provide a minister, but it's our job to analyze what best tool to use. We look at spending and whether that's the best way to approach it, to use a tax. Depending on whether or not it's an environmental objective, we look at regulation. So we put all that on the table, provide the pros and cons, and give that to ministers to decide.
