The taxpayer was able to claim an allowable business investment loss with respect to its investment in a subsidiary that had been incorporated to engage in a speculative business activity that was unsuccessful, notwithstanding that the subsidiary was not wound-up and was amalgamated with the taxpayer more than three years after the year-end at which the allowable business investment loss was claimed. The company was not wound-up or dissolved because of the threat of legal proceedings against the subsidiary, and the double-tax benefit to be derived from a winding-up (i.e., both an allowable business investment loss, and access to the non-capital losses of the subsidiary) made it reasonable to expect that a winding-up would occur notwithstanding that, the proprietor of the taxpayer indicated that, in fact, he never had any intention to have the subsidiary wound-up.
