It's probably related to recruitment and staff retention. Expertise is in high demand in a number of sectors, such as health and social services and economic development. So the two departments are probably facing challenges recruiting a skilled workforce that can provide the very wide range of programs and services they have to deliver. It's also a matter of retaining key personnel, who are also in high demand. Those would be two good reasons.
So I don't have the exact reasons, but those would be very good questions to ask both ministers when they appear before the committee.
