In most cases, no. However, it is the body you will be submitting the translations to that will say whether or not this is a requirement. For example, this is not necessary for immigration purposes, but many universities will ask that the translator declare that they did the translation based on the original document. ICBC requires that translators see original driver’s licences. If I do need to see the original, you can bring it to me so I can verify it when you come pick up your translation.
