Human rights law in Canada has determined that a family’s status is extended to the family caregiver’s responsibilities. This means that, as an employer, there are legal obligations to try to accommodate your employee. A common example of an accommodation for a caregiver could be providing flexible work hours.
There are employment laws that do provide job protection for caregivers such as family medical or caregiver leave depending on the province where you are located. Please consult the provincial legislation that’s specific to you.
