Do I need to reapply for a visa if my work permit gets canceled while my visa is still valid?

This is happening to me right now, the work permit and visa are cancelled, you have 10 days to reapply for new visa and work permit or leave.

Your Work Permit is a booklet that allows you to work, not to stay inside the country. For staying inside the county you need the Visa and that Visa is valid till the Admitted until date stamped in your passport when you entered the country. Do you have a Multiple Entry Non Immigrant B visa, because I not understand a proper visa not 90 days and it is valid till Mar 2019. So or do you go every 90 days to a border and activate a new 90 days period or do you have an Extension of Stay and report to Immigration. To help you, look at these two pictures and compare with what is in your passport with the date of Mar 2019.

If you stop working on Sep 30, than your work permit must be cancelled on Sep 30 not around October 7, the big question is now are you on an actual Visa and doing border runs every 90 days or are you on an Extension of Stay and report to Immigration every 90 days?
