I'd be surprised if those turned out to be more specific or helpful than the generic answer given in
https://www.canada.ca/en/immigratio...l-change-gender-identifier.html#step1-primary
A copy of
one of the following primary identity documents:
- your valid passport or travel document or
- the passport or travel document you had when you became a permanent resident (if applicable, include the passport page that was stamped when you arrived in Canada and became a permanent resident) or
- the certificate of identity or travel document issued by the Minister of Immigration, Refugees and Citizenship Canada or a foreign country.
In exceptional cases, if it is impossible for you to obtain any of the above, you must provide a:
- copy of any identity document issued outside Canada before you came to Canada or
- statutory declaration signed by you attesting to your identity and a statutory declaration also attesting to your identity
As per the above, I would guess not - a CoPR wouldn't qualify as a primary id doc as it's not a travel doc and, being issued by Canada in Canada, it also doesn't qualify under the exceptional cases. Also, CoPRs are usually valid for one year, while PR cards are for five, so if your PR card is already expired it's probably the case that the CoPR technically is expired as well. (On the flip side, if you are able to add it as an extra, no harm in including it.)
Agreed, this is probably the easiest way to comply. Unless we're dealing with a refugee case, in which case I guess a copy of the Canadian refugee travel document should be sent along with the original expired passport that was already sent - and if applies to OP but OP doesn't have a RTD yet, then
