A fully funded PhD admit (26K CAD/year) applying under SDS asked whether to attach family members' bank statements on top of the required documents. What members clarified:
- SDS has a short, fixed checklist. Members listed it plainly: GIC, first-year tuition paid, language test, and the university offer. Once the GIC and tuition are paid, 'you have almost completed the requirements.'
- A funding letter can't substitute for paid tuition under SDS. The applicant's university confirmed this: even with full funding, SDS requires the first-year tuition actually paid up front — it's refunded to the student after arrival. Budget for that cash-flow hit.
- Extra family financials are optional, not mandatory. Members agreed there's no SDS provision requiring supporting relatives' bank statements. If you include them (affidavit of support, job letters, salary slips, bank statements), attach them as optional documents.
- If you attach extras, explain them in the SOP. The consistent advice: supplementary financial documents only strengthen the file when the SOP clearly ties them together — who is supporting you, with what, and why.
