The introduction of Ontario’s Fair Workplaces, Better Jobs Act, 2017 (formerly Bill 148) has left many employers trying to understand and apply the legislatively required changes to their workplaces. One change causing considerable confusion is the revised vacation provision for long-tenured employees under the Employment Standards Act, 2000 (the ESA). Formerly, all employees were entitled to a minimum of two weeks’ vacation (with some caveats and conditions) and four percent vacation pay; effective January 1, 2018, the ESA requires that employees with five years or more service with a company receive three weeks of vacation and six percent vacation pay. Many employers are full of questions, though: When exactly can employees begin taking that extra week? When do they earn it? How does the third week change vacation pay?
