On June 12, 2022, updates to the provincial Highway Traffic Act Regulation 555/06 (Hours of Service) will come into force. These changes will make it mandatory for commercial motor vehicle drivers who operate within Ontario to use an Electronic Logging Device (ELD) to record their hours of service (HoS). Drivers of commercial motor vehicles who are currently required to maintain a daily log will be required to use a certified ELD.
