From the National Post:
An Ontario court decision recognizing the legality of same-sex marriage lets a bizarre legal tactic out of the closet: the possibility of marriage between a human and a corporation. Professor Bruce Welling, corporate law expert at the University of Western Ontario, says that since corporations are endowed with the same legal rights as humans, the new definition of marriage makes it possible for a human to marry an Ontario corporation. Ridiculous as it might sound, a marriage between a corporation and a person could offer special benefits. For example, the happy couple could gain access to spousal tax credits, the right to claim support in a legal separation, maybe even pension benefits.
