There isn't an official freeze.
However, I have asked each of the service chiefs to consider departures as an opportunity to reassess their needs. In some situations, for example, it might be more advantageous to reassign an employee elsewhere, or even to another service. Once again, that would be for the purpose of meeting needs and complying with priorities that are evolving.
I don't want to see systematic hiring to replace employees who leave. It must be determined whether we still need the position in question. We may need an employee, but elsewhere and for other duties. That's why I'm reluctant to tell you that there is a freeze. However, there is definitely a careful reassessment.
