T3 but no T5008 - why?

I received a T3, Stmt of Trust Income Allocations and Designations. It reports a Capital Gain in box 21 but I have not received a T5008. This is a non-registered mutual fund account from a financial institution. I looked at the T slips for importing from CRA and don't see a T5008. Why is that? Is it possible the T3 capital gain is net of ACB?
