@linhlinh9988 It can go either way. Some t5008s will come without cost. This is typically (but not always) because some investments (those structured as trusts) do not issue T3 slips until end of March (when due) but t5008s for cap gains are due end of February. As some investment distributions can affect ACB (return of capital vs dividend, etc) they therefore may not possibly be able to calculate it
