Supreme Theatres Ltd. v. The Queen, 81 DTC 5136, [1981] CTC 190 (FCTD) -- summary under Canadian Investment Income

After noting (at p. 5138 (DTC)) that "there is a presumption that, since the purpose of a corporation is to make profits from carrying out its business objects, the income received by a corporation is business income," Gibson, J found that rentals received by the taxpayer company, whose business was the operating of motion picture theatres, the lease of a Theatre to a Lion's Club and of land and drive-in theatre facilities as well, were active business income and thus excluded.
