This is Neal Leblanc. I'm the director of CPP policy and legislation at Employment and Social Development Canada.
At the moment, the information being collected by the Minister of National Revenue and shared for the purposes of the Canada pension plan is only the data necessary to calculate benefits. It's effectively information related specifically to pensionable earnings to CPP and contributions, in addition to some very basic demographic information.
The goal of this is to put us back where we had been in the past when we had access to data that allowed us to see a more fulsome picture of Canadians to get an idea, for instance, of how much the Canada pension plan represents of that person's total income in retirement.
It would put us in the same position that the old age security pension program and employment insurance employment program are in, in terms of being able to use other data collected by CRA in order to do program evaluation and policy work.
