The Supreme Court of Canada's Decision in Queen V Cognos

The Supreme Court of Canada's decision in Queen v Cognos Inc, which was explained in Case Brief 25.1, supports the proposition that

A) an employer may be held vicariously liable if an employee, who was hired to serve as a bouncer at a bar, viciously beats an unruly customer in a fight that occurred away from the business premises.
B) an employer is generally entitled to summarily dismiss an employee who has been caught watching pornography on the employer's computer during regular business hours.
C) a former employee does not owe any obligations to the former employer once the employment relationship has come to an end.
D) employers have a duty during employment interviews to exercise reasonable care and diligence when making representations about the nature of an employment opportunity.
E) constructive dismissal may occur through either a single unilateral action taken by the employer that breaches the contract, or a series of actions that, taken together, show that the employer no longer intended to be bound by the contract.
