Hi Penna, Screech and everyone!
I wanted to know URL about the information which Penna found. Then I found this,
http://www.servicecanada.gc.ca/eng/about/publication/soc_ins_num_eng.shtml
Social Insurance Number December 2007
What documents must I provide?
If you are a permanent resident, provide one of the following documents issued by Citizenship and Immigration Canada:
・Permanent Resident Card (this is the only acceptable document if you applied for your permanent residency from within Canada);
・Confirmation of Permanent Residence and Visa counterfoil (sticker) in foreign passport;
・Confirmation of Permanent Residence and Visa counterfoil on Single Journey Document for Resettlement in Canada;
・Confirmation of Permanent Residence and Visa counterfoil on United Nations High Commissioner for Refugees Travel Document;
・Confirmation of Permanent Residence and Visa counterfoil on Red Cross Travel Document;
・Record of landing.
??? I'm confused. So, CoPR is OK for getting SIN? Or NO?
Penna, could you tell us the URL you found?
