I personally got my G license exactly like I mentioned.
D. Letters of Authentication
If you claim that you have more than 12 months of previous driving experience on your application form at the DriveTest Centre, you must provide an original letter of authentication to gain credit for all that experience. If you do not provide a letter of authentication, you will get credit for only 12 months of driving experience. The letter of authentication:
- May be acquired from the Embassy, Consulate or High Commissioner’s Office representing the originating jurisdiction, OR from the jurisdiction that originally issued the licence, validating the authenticity of the licence.
- Must be on the originator’s official letterhead paper.
- Must be dated no more than 6 months prior to application date.
- Must clearly state that it is certifying the duration of the applicant’s driving experience and that the licence to which it refers is valid – the licence cannot be expired or suspended.
- If not in English or French, you must have it translated by an MTO-recognized translator.
