The nature of a dormant file means it hasn't had any activity at all in government programs in the past five years. We know they're not being used. Some additional files may go dormant in the future, but they're not showing up in CRA and they're not showing up in EI. They're not making contributions and they're not receiving CPP. It's the nature of the dormancy. They're not being used to access government benefits.
