The Appendix 2 credential options for Pharmacist are a baccalaureate or Licenciatura degree or a state or provincial licence, so a Newfoundland and Labrador licence answers the treaty requirement. The state's own practice licence is a separate professional-regulation matter that the employer must resolve for the job to be lawful.
Two licences answer two different questions
The officer deciding a TN application asks whether the applicant is a Canadian citizen, whether the job is in a listed profession, and whether the applicant holds a credential that profession's line specifies. For Pharmacist, the options are a baccalaureate or Licenciatura degree or a state or provincial licence, and the provincial licence meets the rule. The officer is not the state board of pharmacy, and admission in TN status does not authorize dispensing in a state where the pharmacist is unlicensed. The hospital's credentialing department should confirm which pathway applies to a Canadian graduate and whether a temporary permit allows supervised work while the full licence is pending. Get that answer in writing and include it, because an offer that assumes immediate practice in a state where she cannot yet practise will read as an incomplete plan. If the state pathway takes longer than the hospital expects, the start date should move, not the file.
Hypothetical example: a Canadian land surveyor is offered boundary-survey work by a U.S. engineering firm. The first review should match the offer's field and mapping duties to the Surveyor profession and compare the credential named on that line with the surveyor's actual licence or degree. The written state-board response settles whether independent signing authority is available at arrival. If local rules require supervision first, the employer letter should describe supervised duties and the planned licensing sequence rather than imply unrestricted practice.
