Does relying on a family member's support instead of social assistance avoid financial inadmissibility?

It can, since the underlying concern behind this ground is reliance on social assistance, not simply having modest personal income. If a family member's support genuinely means the applicant won't need to turn to public assistance, that can address the core issue the officer is assessing, even where the applicant's own resources would otherwise look thin.

The key word is "genuinely." An arrangement that looks credible on paper but isn't backed by real, ongoing capacity to provide support won't hold up, and officers are alert to support claims that seem designed only to get past this particular concern rather than reflect an actual, sustainable plan. This is especially relevant where the family member's own finances are limited, uncertain, or dependent on circumstances that could easily change.

It also doesn't eliminate the need to look at the applicant's own situation entirely — an officer may still consider whether the applicant is capable of supporting themselves and whether relying entirely on someone else long-term is realistic. Anyone planning to rely on family support to address a financial inadmissibility concern should document the arrangement thoroughly and be ready to explain why it's sustainable, not just present it as a stated intention.
