My interpretation of the above mentioned orders is that COPR is allowed to travel based on following findings:
1) PR/Citizens are allowed travel.
2)immediate family members of PR/Citizens(point one above) are allowed to travel.
3) immediate family includes spouse/children/dependent
4)obviously immediate family members will not have PR/Citizenship, otherwise it they will fall in the category of PR/Citizens (point 1 above) and there is no sense of raising point 2 above.
[in simple words, if family members have PR/Citizenship, there is no point of separately mentioning that immediate family members are allowed]
5)immediate family members should have a document other than PR/citizenship through which they are allowed to travel. And This document is obviously COPR.
=> conclusions, immediate family members with COPR are allowed to travel.
Note:
1) "Indians as per indian act" are NOT people of India/Bharat. Indian act is a Canadian act.
2) I'm not an expert/agent. All are just interpretations
