I don't disagree with Andrew that there are some differences between the various lines, but they are important ones. More important is to recognize the different effect on different households. If you have two seniors who are both receiving GIS and OAS, it's a very different circumstance than if you have a single elderly person who's only receiving GIS. Those circumstances should be treated differently.
In addition, the data is clear that the cost of living varies considerably from city to city. If you're a low-income senior in Vancouver on GIS and OAS, it's a very different circumstance than if you're from my hometown of Windsor.
I would love to see a discussion about curtailing OAS—clawing it back more aggressively and freeing some of those resources to better target GIS. How do we do a better job? I'd be more than open to discussing augmenting the benefit for single elderly people. Given the demographic deficit we're facing, we have to use scarce resources better. My view is that having a full benefit of OAS on the individual level up to $70,000 is not a well-targeted program.
