The trick on SIN, the real trick on outcomes, is not just measuring employment but income levels as well, and for that we have to link it to the CRA database.
Now we're not able, obviously, to do that in a direct way, by tracking a specific individual, so the work that had to be done was on linking the information we have on EI and SIN and the CRA database on an anonymized basis that met all the privacy standards. This was not just to give us a global result that would allow us to say of the people in the program that their average income was x; the tricky part was working through how the model could kick out for us what the results were after two years, three years, four years, on the income for individuals who had these types of interventions—literacy training, etc.
That was extremely tricky to work through, and that's what has been, in fact, worked through. It isn't just an awareness of employment. That's the other thing. For the self-employed, knowing the SIN number doesn't tell you if they're actually with an employer who's issuing slips to them at work. If they're self-employed it's different. Because of the diverse clientele, we think this linked database is the best way to get at the data that the Auditor General has rightly said we need in order to track not just how we're doing now but how those individuals do over time, but it is tricky.
