The guaranteed income supplement is the income-tested portion. The increase that took place in July of 2016 was $947 per month for the lowest-income single seniors. It was directed to single seniors, because the data shows that while old age security and GIS combined can raise most couples who are recipients out of low income, that's not the case for all single seniors. That's why it was directed to the lowest-income single seniors.
You're right, there were 13,000 single seniors raised above the low-income rate, and of those 13,000, 12,000 were women, so it's certainly supporting poor women. For those who were not raised above the low-income cut-off, which is a measure that we use within Canada, the depth of poverty for those who still remain below the low-income cut-off was reduced by 23%, or $723 per year. So 900,000 Canadians benefited from it, and 13,000 were raised above the low-income cut-off.
