I represent workers at the immigration departments and Service Canada, so I can only speak to anything that would happen in those three departments. As far as we are aware, aside from 1-800-O-Canada, there was other call centre work that Service Canada—for example, during CERB—outsourced as well.
We were able to successfully end the contracting out of that by doing some significant advocacy with the employer when we became aware of the contracts. I cannot speak to departments other than those because I don't represent those other workers.
