What break and rest period rules apply to Ontario employees during a shift?

The Employment Standards Act, 2000 requires most Ontario employees to get an eating period of at least 30 minutes after every five consecutive hours of work, so they're not required to work an unbroken stretch beyond that without a break. With the employer's agreement, that 30-minute period can be split into two shorter breaks instead of one continuous one, but the combined length still needs to add up to at least 30 minutes.

This eating period is generally unpaid unless the employee is required to remain at their workstation, on call, or otherwise not genuinely free to use the time for their own purposes, in which case it may need to be treated as paid working time depending on the circumstances. Beyond this specific eating-period requirement, the ESA doesn't set out additional mandatory rest breaks during a shift, though employers can offer more generous breaks than the statutory minimum if they choose to.

Employers should also keep in mind that separate rules under occupational health and safety legislation address rest in the context of specific hazards or working conditions, which is a different regime from the ESA's break requirements. If your scheduling doesn't build in the required eating period, that's worth fixing regardless of how the workday is otherwise structured.
