When bilingualism is required for a given position, then that requirement is respected. Otherwise, the candidate cannot be appointed unless the appointment is what we call non-imperative, and in those cases, the candidate has a certain amount of time to meet the requirement. Obviously, if the job is only for three months, the candidate will not get any training. The employer is responsible for specific term positions that are excluded. For example, at Statistics Canada, there is a clear timeframe for census activities. We know that at certain times, there will be no jobs available.
