When can a corporation be represented in court by a sole director, officer and shareholder?

When considering the interests of justice, and access to justice generally, it is readily observable that individuals have the right to represent themselves in court and corporations do not. Courts have commented on this apparent inequality and the difficulty in rationally supporting such different treatment, at least when dealing with a closely held corporation. As Quinn J. observed in Lamond v. Smith (2004) 11 C.P.C. (6th) 104, where a corporation is closely held and there is a sole director, officer and shareholder, it is hard to justify not allowing that individual to represent a company in view not only of the right of individuals to represent themselves, but the prevalence of individuals representing themselves in our courts.
