Here is what I see,

your Adjusted Cost Base was 1.36 based on 24,523 shares for a book value of 25,764

after buying 5700 shares at 4.52

ACB = 1.96 based on 30,223 shares for a book value of 59,181

The sale of 5700 shares at 4.51 would have resulted in a realized gain of 25,764

Your capital gain would be caluculated:

(25,707-(5700*1.96))*50% = 7,267.50

If you slod another 5700 shares at the same price, your capital gains would be double at 14,535

If you are in Winnipeg, it would pay for you to go to their office on Broadway and see if you can get a ruling on the disposition of your shares. A mistake was made, and sometimes they do make allowances for them. You need to see them, don't call as your call is important to them, do hang up.

Good Luck, Andy

PS . This would mean you will pay less capital gains in the future, but that won;t matter when you cash in your shares at 22.00 (i am an optimist)
