Why didn't adding capital gains change the refund calculation?

[coukellg]

I made a large RRSP contribution to offset capital gains from the sale of shares in a small business corporation.  After entering all information except capital gains, TurboTax showed a large refund.  When I added the capital gains, the refund amount didn't change.  It seems like there is no additional tax being calculated on this capital gains income.

You capital gain seems to be a QSBCS shares, therefore there are exempt from capital gain (assuming you have still room left)
