Generally speaking, the members we represent need the GIS because they are not receiving a pension from their employer. Nevertheless, it can't be denied that the government introduced this measure to support retirees, and based it on an economic indicator.
Is it the right one? I believe that it's at least a first step. The economic indicator chosen by the government was the Canadian poverty line. In other words, the incomes of retirees below the poverty line were raised to the Canadian market basket measure threshold.
Now you're asking me whether the government should save money by not providing this 10% increase to those at the market basket measure threshold. I'm appalled. They are living at the poverty line and it's tough going.
