According to the
BC Employer Guide, the company does not have to prove recruitment efforts if:
"you have a valid work permit and/or employment authorization and are currently working fulltime (at least an average of 30 hours per week, year-round) for the supporting B.C. employer in the occupation identified in the job offer. Please note that if you are currently working fulltime for the supporting employer on a co-op work permit or a study permit, this requirement will only be considered met if you have completed your program of study."
