No you have to report your investment sales in the tax year you make them - regardless whether they resulted in a loss or in a gain.
But capital losses may be used to offset other capital gains not only in the current year but they may also carried over into past and some future years as well (if not used). If you are interested in doing that talk with your accountant.
OurRealtor, no disrespect, but looking at the multitude of questions that you asked here, you really need to talk to an accountant. As informative as the posters are on this forum, they are not a substitute for professional advice. If you want to save yourself an audit by CRA, hire an accountant.
