A friend of mine under CEC stream. She went back NZ with WP and work from home there while waiting for COPR. She received COPR but when they find out she is out of Canada, they withdraw it and tell her she will get that when she come back to Canada.Yes, you can work from India. Once you move out of Canada, inform IRCC that you no longer are in Canada and update your address. However, if you are not in Canada, you will not be able to renew your PGWP under the new policy or apply for a BOWP, for which you have to be in Canada, so keep that in mind.
Hope it could help you. I think it is better to make a call
