Yes, that is what the bill provides. When the proposed changes come into force, they may be retroactive to November 20. Benefits had already been extended, by regulation, from October 23 to November 20. The purpose of this bill is to extend them further, from November 20 to May 7. Once these changes come into effect, workers will have 60 days to file a claim if they were affected during one of these weeks.
