No. This is what we are attempting to do with the CRA—with a great deal of success—through a process of processing of transactions at PSPC. If it's determined that we have to issue a revised T4 for the individual, we do that. It's transmitted automatically to the CRA or to Revenu Québec for an automatic reassessment of the tax file without the individual employee needing to refile or to engage either with PSPC or the CRA. The employee then receives the updated notice of assessment from the CRA, and is also able to access through Phoenix or through his or her CRA My Account any updated T4s issued by PSPC.
