Researchers have done all kinds of work on the issue, but it's more a government decision. In those countries like the U.K. and Ireland that have chosen to identify a particular measure, it was a government decision.
So I think the advantage of what Canada as well as other jurisdictions have done is that we have provided a basket or a range of measures that the government could use, and they're all using them toward helping to make the best choices in terms of the design of programs and benefits for them.
Regarding Quebec and Newfoundland—from what I understand, Quebec is using the international low-income measure.
