The Canada Recovery Caregiving Benefit provides $500 ($450 after taxes withheld) for up to 44 weeks per household for workers:

• unable to work for at least 50% of the week because they must care for a child under the age of 12 or family member because schools, day-cares or care facilities are closed due to COVID-19
• because the child or family member is sick and/or required to quarantine or is at high risk of serious health implications because of COVID-19.

This benefit is available until May 7, 2022.
