This is the official clarification of new ban which states that immediate family members of prs are also allowed and also people having copr and PRVs , who are travelling to reunite immediate family members can also enter canada( i may be wrong on this one check it yourself guys, correct me if i am wrong).
Now the only thing i guess would be to convince airline guys at the airport about this official annoucement.
I had sponsered My wife and my 5 month old son as pwemanent residents and they are coming this sunday . I am gonna tell her to bring everything ( marriage certificate, photocopy of my pr card, marriage photos, and photocopy of this official announcement etc.) So that airport crew will not have any reason to deny their boarding.
