There is no obligation to be in Canada to renew the PR card
This is according to CIC operational manual and the regulations for the immigration act.
You can not apply in a VISA center/embassy/consulate abroad.
You must provide a CDN mailing address for correspondence.
And you must pick the card in person IN Canada.
ENF 27 R56(2)
Applications cannot be refused solely on the basis of
evidence that the applicant was not in Canada when the application was filed.
R56(2) states clearly that a PR card application must be made in Canada. Furthermore,
the card must be delivered in person to each applicant, pursuant to R58(3), and be
picked up within 180 days of the person receiving notification that it is ready for collection.
This enhances the integrity of the application process, allowing the local office to contact
the client to review documentation and assess residency issues in person. However, it is
recognized that the Regulations do not specify physical presence in Canada for purposes
of filing a PR card application. http://[flash=200,200][flash=200,200][u]Applications cannot be refused solely on the basis of

to provide additional information or to present themselves in person for the purposes of
reviewing either identification or eligibility for the PR card. The CPC may refer a case to a
local CIC if all or part of the application originated from outside Canada, and if there are
questions as to the client's identity, status or residency history, or the authenticity of the
documentation. Clients must report in person to pick up their card in Canada, in
accordance with R58(3
