In Ontario the only legally required breaks are 30-min unpaid meal breaks. You must take one for every 5 hours worked, and cannot work more than 5 consecutive hours without one. 15-min breaks are considered a courtesy at the employer's discretion, but not required by law.
No, the ESA in Ontario doesn't require a 15-minute break for shifts of four hours or less. It does, however, require a 30-minute meal break after five hours of work.
Basic Entitlements In an 8-hour shift, the ESA requires that an employee be given a 30-minute meal break. This break must be provided within the first 5 consecutive hours of work. If you work an 8-hour shift, this means you are entitled to one uninterrupted 30-minute meal break.
For an 8-hour work shift, employees are entitled to a minimum 20-minute uninterrupted break if they work more than six hours. The break should not be taken at the beginning or end of the shift, and employees must be allowed to take it away from their workstation.
It is correct that your employer has to provide you with a meal break in ance with the Employment Standard Act. It's not something that can be opt-out of except by express agreement between employee and employer.
For a 5-hour shift in Ontario: The ESA requires that employees be given one 30-minute break for a five-hour shift. You can use this break however you like, and your employer can agree to split it into two 15-minute breaks. Employers are not required to provide more than 30 minutes of break time for a five-hour shift.
