Congratulations!
AFAIK, there are no instructions from IRCC for post march 2020 copr holders as of now. There maybe instructions with COPR
There are some rules that exempt post march copr holders from travel restrictions and allows them to land.. check canada.ca
In my view, with all the hotel thing and option email, this is good news as they may be thinking of removing travel restrictions to post march copr holders..
Congratulations, can you send me the email to contact IRCC, my COPR was expire in march
