What Qtrade provides
Qtrade posts tax slips and statements in its online portal and lets you download your transaction history per account. For non-registered accounts you’ll generally receive a T5008 covering your dispositions, along with T3 and T5 slips for distributions and dividends. Trades inside a TFSA or RRSP aren’t reported and aren’t taxable.
Why the cost base may be incomplete
Like every broker, Qtrade can only compute cost base from activity it sees in your Qtrade accounts. If you transferred shares in, hold the same security at another broker, reinvested distributions, or received equity-comp shares, its cost figure can be partial or blank — while the proceeds are usually reliable.
A Qtrade detail worth knowing
If you’ve transferred holdings into Qtrade from another institution, the cost base shown may reflect the transfer-date value rather than your true pooled ACB — override it with your real cost.
Getting your data into shape
Export your Qtrade activity (transactions and slips), then build a pooled cost base across all your accounts and brokers — applying reinvested distributions, return of capital, FX on US trades, and any corporate actions. That reconciled ACB, not the raw slip, is what belongs on your Schedule 3.
