International Driving Licence is not accepted as a valid proof by the Canadian Ontario Province (Don't Know about other province) to explain the authenticity and driving experience. MY IDP was rejected as a valid proof and they accepted the other proof of authenticity which was issued by the driving Authority in India which is called Particulars Letter and told me that I can give G1 and get G license if I passAwale said:Today i went to Vehicle and licencing auhority to get the authentication letter with National DL and IDP.. They told you do not need a letter IDP will serve the purpose. Is that correct?
