No. Often it's connected to the position. Approximately 80% of our positions in the department are considered bilingual. When people move from one position to another, they have to meet the language requirements of the new position, whether they are Francophones interested in a position requiring knowledge of English, or the reverse. If proficiency in the language is imperative, there will obviously be a problem, but language training is offered based on the priority of the positions involved.
