Maternity leave and other special leave benefits continue as they were originally structured. That is the required number of hours, and they operate within the current EI system. The government has signalled that if individuals are already on maternity leave, for example, and come off maternity leave during the period when the CERB benefit is in place, they would be eligible for the CERB. However, if an individual does not have enough hours under the currently structured EI rules, they still need to receive sufficient hours to qualify for the benefit. That is something that Minister Qualtrough has said she is looking at.
