A letter that states the profession, the duties in each phase, the dates covered, the compensation arrangement, and the temporary nature of the appointment. Degree documentation supporting the listed profession's credential requirement should be assembled alongside it, in the form the applicable listing calls for.
Build the file around the two phases
Collect the appointment or contract document, the department's support letter, and the credential records the profession's listing requires. Where the design phase has its own compensation or a separate agreement, include it rather than leaving it to be explained verbally. Keep the paper consistent: if the contract says one start date and the letter another, expect that difference to be the first thing noticed.
Each child needs documentation of the qualifying relationship to the principal, typically a birth certificate naming the parent, alongside their own valid passport. The biologist entry on the professionals list requires a baccalaureate degree, and the regulation asks whether the degree is in the profession or a closely related field. A credential evaluation is required only for degrees from outside Canada, Mexico or the United States. Keep the offer, credential evidence, and ownership explanation consistent so that a later question does not expose a different arrangement.
