Well, we're using the straight calculation of approximately 6.7% of Canadians today living in poverty, out of the number of 4.9 million seniors at the last census, so that brings us to about 300,000 people today. Those are the people under the official poverty line, not those who are near poverty.
If we do nothing and the senior population increases, as projected, to 6.7 million by 2023, and the rate of poverty stays the same, that's how we get to the 500,000.
