Ontario produces most of the reported case law. The Employment Standards Act, 2000 adds statutory severance pay under s. 64 for employees with five or more years of service, where the employer meets the payroll threshold or severs 50 or more employees within six months because part of the business closes. It is calculated under s. 65 at one week per year of service, up to 26 weeks. Benefit plan contributions must also continue through the statutory notice period under s. 61(1)(b). Ontario employees must choose between an ESA complaint and a civil action for the same termination (ss. 97 and 98), so the release should confirm that no complaint is pending.
British Columbia relies on s. 4 of its Employment Standards Act, which voids any waiver of statutory requirements, and on s. 63 for compensation for length of service, which starts after three consecutive months of employment and is capped at eight weeks. Those weeks are paid before, and independently of, any release. A private settlement does not automatically bar a complaint before the BC Human Rights Tribunal, so employers should name the Human Rights Code specifically and document the legal advice offered.
Alberta applies s. 4 of the Employment Standards Code, which treats any agreement to opt out of the Code as void. Statutory termination notice under s. 56 ranges from one to eight weeks depending on length of employment, and vacation pay owed under the Code must be paid on termination, not traded for the release. Claims under the Alberta Human Rights Act should be named expressly, as in the other provinces.
Quebec follows a civil law model. A release is a transaction under arts. 2631 and 2633 of the Civil Code of Québec; it binds the parties as res judicata, but it must be homologated by the court before it can be enforced. Article 2092 prevents an employee from renouncing in advance an indemnity for insufficient notice, yet a transaction signed after termination is valid. The Act respecting labour standards is of public order (s. 93), and an employee with two years of uninterrupted service may complain to the CNESST under s. 124. That complaint must be filed within 45 days of dismissal, and the transaction should address the remedy expressly.
Federally regulated employees fall under the Canada Labour Code, which grants statutory severance under s. 235. Non-unionized employees other than managers, with twelve months of continuous service, may file an unjust dismissal complaint under s. 240. That complaint must be filed within 90 days, and a release signed with fresh consideration is the employer's main defence.
