“The Ontario government has announced that it will reverse a Bill 148 amendment on the calculation of public holiday pay. The Bill 148 amendment, which came into force on January 1, 2018, was highly criticized by employers as costly and confusing. For example, the Bill 148 calculation required the payment of a full day of pay to any part-time worker who worked just one day in the pay period preceding the holiday. If that part-time worker had two part-time jobs and worked one day at each job in the preceding pay period, he or she would receive two days of pay for one public holiday.  Ontario Regulation 375/18 will revert to the prior calculation for public holiday pay in Ontario for provincially regulated employers.”
