They're independent things. The Labour Force Survey is the official source of the unemployment statistics you hear about every month. We ask people whether or not they have jobs. If they don't have jobs, were they looking for work and were they available to take jobs? Regardless of whether you're on employment insurance or some sort of social assistance, if you fit those criteria you're unemployed. So it's measured independently.
