I AM TRAVELLING ALONE TO CANADA FOR MY STUDIES ON 27TH AUGUST . I AM 18 YEARS OLD AND DID NOT HAVE TO SHOW THE CUSTODIANSHIP FORM FOR MY STUDY PERMIT/TRV . SO AM I SUPPOSED TO HAVE A GUARDIAN WITH ME OR IN CANADA ? OR SHOULD I JUST CARRY A LETTER SIGNED BY MY PARENTS WITH ME ? THANKS FOR THE HELP :D
