July 9, 2018
As of July 1, 2018, a new regulation recently introduced by the Ontario government comes into effect that reinstates the previous formula for calculating public holiday pay prior to more recent changes under Bill 148.

For public holidays that occur after July 1, 2018, the amount of public holiday pay to which an employee is entitled is all of the regular wages earned by the employee in the four work weeks before the work week with the public holiday plus all of the vacation pay payable to the employee with respect to the four work weeks before the work week with the public holiday, divided by 20. The Ministry of Labour offers a Public Holiday Pay Calculator online at Ontario.ca/ESAtools or find more information at Ontario.ca/publicholidays.

The change generally applies to all employees covered by the Employment Standards Act.
