Summary: Mass Layoff Rules in 2026
In Alberta, a mass layoff (legally known as a “group termination”) is triggered when an employer terminates 50 or more employees at a single location within a 4-week period.
With major restructurings currently hitting the Calgary energy sector — including the 900-job reduction announced by Imperial Oil — it is critical to understand that your rights in a mass layoff often exceed the standard “minimums.”
The “Crowded Market” Factor
When hundreds of people in the same industry are laid off at once, finding a new job takes longer. Alberta courts take this into account. In a mass layoff, you may be entitled to increased common law severance because your “difficulty of re-employment” is significantly higher.

When Do Mass Layoff Rules Apply?
Under the Alberta Employment Standards Code, “group termination” rules are triggered if:
- The employer terminates 50 or more employees.
- The terminations happen at a single location.
- All terminations occur within a 4-week period.
Note: These rules do not apply to seasonal workers or employees hired for a specific, time-limited project.
Special Notice Requirements for Employers
When a mass layoff occurs, the employer has additional legal obligations to the government and the workforce:
- Notice to the Minister: The employer must notify the Minister of Labour at least 4 weeks before the first termination takes effect.
- Notice to Employees: Employers must provide at least 4 weeks’ notice to affected employees (or pay in lieu), regardless of their length of service. Note: If an employee’s individual tenure entitles them to more than 4 weeks (e.g., 8 weeks for 10+ years of service), the higher amount applies.
- Union Notification: If the workplace is unionized, the union must be notified in writing immediately.
Mass Layoffs and Common Law Severance
A common mistake employees make in a mass layoff is assuming the “group notice” is all they are entitled to. While Employment Standards provides the floor, Common Law provides the ceiling.
In a mass layoff, your severance calculation is impacted by the economic climate. Courts recognize that if 100 oil and gas engineers are laid off in Calgary on the same day, your ability to find a comparable job is significantly hindered. This often results in “exceptional circumstances” that can push severance packages in Alberta to, or even beyond, the standard 24-month maximum.
