Authentication letter without letter head of the authority issuing it, is not entertained in drive test location in Toronto/ Bramption. Visit MTO and they will also send you back. I can say all this because it happened with me. I had to stand in que 2 times for 2 hours and was sent back. They just dont agree to take it. Rubber stamp at bottom means nothing for them. So then I called my family back home and they got it on letter head. All this took 2 months.
The letter should contain your name, fathers name, DOB , Address, date of issue , date of expiry, licence number and can include something of no traffic violation ( not must) as per record. Now dont forget that here in Ontario they check Drivers Linence with Passport details, if their is variation in spellings of name they will not take it, similarily on DL last name is different from passport they will not take. Short names - they dont take. Name should be exactly matching with the passport.
I am sending my authentication letter as sample :
LETTER HEAD , LOGO OF AUTHORITY, REF NO, DATED, TELEPHONE NUMBER
