The Ontario Court of Appeal decision states that:
Canada Post is a Crown corporation established to provide universal mail service in Canada—a lightly populated, but geographically vast country. CP is required to provide mail service to all points in Canada, however remote, at reasonable cost, but in a financially viable way. CP charges a uniform rate for its various classes of service. This uniform rate has been a tradition of the Canadian postal administration since it began and remains a core component of CP's system.
