Key legal question
Whether the respondent's participation in the building consortium generated income from self-employed activity subject to AVS contributions.
Extracted holding
The consortium participation was a mere capital investment in real estate; no self-employed activity was shown, so no AVS contributions were due on the income.
Extracted reasoning
A mere consortium participation does not by itself establish self-employment. On the binding facts, the respondent did not go beyond passive co-ownership/investment; the income consisted essentially of rental proceeds from property held for asset management.
