In Canada, at tech startup seminars, the lawyers remind us that the government has a "Ministry of Labour", and it is NOT called the "Ministry of Employers" for a reason. Lawyers advice employers to make the employee happy, or risk costly battles due to a complaint to the Ministry. As far as I know, you are legally entitled to either termination pay or advance notice, and holding it ransom as coercion to sign some agreement would be very risky.

Apparently some companies still download employment agreements off the web that have the "at will" clause but this makes them invalid.
