可以, but you need to report your capital loss in 2008
Generally, if you had an allowable capital loss in a year, you have to apply it against your taxable capital gains for that year. If you still have a loss, it becomes part of the computation of your net capital loss for the year. You can use a net capital loss to reduce your taxable capital gain in any of the three preceding years or in any future year. To do this, claim a deduction on line 253 of your return.
The net capital losses of other years generally may be applied against taxable capital gains in the current year. Your available losses are shown on your Notice of Assessment or Notice of Reassessment for 2007. Your notice will show your prior-year losses and your current year loss after adjustment. You only have to add those two amounts to calculate your total net capital loss available for 2008.
