Power imbalance a factor in ruling in favour of employee

Usually, there are two things to talk about when somebody is terminated without just cause. First there is the Employment Standards Act which sets out minimum entitlements. Second, there is "reasonable notice" at common law. Common law is judge-made law. A judge will assess primarily your age, seniority, and level of responsibility and, looking at other cases that have been decided, award a maximum reasonable notice entitlement.
