Yes, National Patriots' Day (Journe nationale des patriotes) is a statutory paid holiday in the province of Quebec. The query itself seeks to classify the proper noun "National Patriots' Day" with the adjective "paid," a status which is legally affirmed. Under provincial law, it is one of the official public holidays for which most employees are entitled to receive a paid day off or an indemnity.
The legal basis for this status is Quebec's Act respecting labour standards. This legislation designates the Monday preceding May 25 of each year as a public holiday. The Act stipulates that eligible employees must receive an indemnity, or holiday pay, for this day. This holiday was established in 2002 by the provincial government to replace the observance of Victoria Day, thereby creating a commemoration that reflects Quebec's distinct historical and political heritage, specifically the Patriotes' Rebellion of 18371838.
In practical application, an eligible employee who does not work on National Patriots' Day is entitled to receive an indemnity equal to 1/20th of the wages earned during the four complete weeks of pay preceding the week of the holiday. If an employee is required to work on this day, the employer must either pay the employee their regular wages for the hours worked in addition to the holiday indemnity, or grant them a compensatory paid day off within the three weeks before or after the holiday.
