I am handling skilled immigrants in Canada, and the consulate asked me to submit a letter of recommendation for work. Do you need notarization? Do I have to submit my direct supervisor's business card? Federal skilled immigrants do not need notarized job recommendation letters, but Quebec skilled immigrants do. Provide business cards when it is convenient, and do not provide them when it is inconvenient. The federal recommendation letter has not been notarized and does not need to be stamped with the official seal. So you don't have to let the company know, but you have to have the signature of the referee. Quebec should have a signature and official seal, because it is notarized. Tell the company that you need a professional title recommendation letter or something, and find a reason for the company to seal it.
