Yes. This should be communicated to their academic supervisor, organization partner and academic institution. Their fellowship will be put on hold for this period of time, and they will not be paid from your fellowship. Once a return date has been determined, they will need to inform Mitacs of when they plan on returning to the fellowship to complete their term. A Request for Leave form (found in the downloadable Application Package zip file in the How To Apply section) must be submitted to to request to put the fellowship on hold.
