This is a management right of your employer. Under the “Regulation respecting the keeping of a system of registration” of the Parity Committee, it is up to the employer to keep an up-to-date register which must contain the number of hours worked per day for each employee, with the precise time that the work began, was interrupted, resumed and was completed. Consequently, the employer may require that you submit time sheets. It is strongly advised that you make note of the dates, times and locations for each shift you worked.
