Hudon v. Canada, 2001 DTC 5630, 2001 FCA 320 -- summary under Business

In the years in question a corporation which owned forest concessions and rights to develop the hydro electric potential of a river was engaged in negotiations with Hydro-Quebec and other activities with a view to developing that potential. Desjardin J.A., before going on to find that the taxpayer was engaged in a business, noted that the word business was defined to include an undertaking of any kind whatsoever and also noted that the determination of whether a taxpayer was engaged in an active business was a mixed question of fact and law.
