What is the age to be able to leave the country by driving?
You will need a letter from your parents giving you permission to travel across the border because you are a minor, anyone under the age of 18 is considered a minor. Even though you are going with your brother you will still need your parents consent. Canada takes minors traveling with out their parents very seriously, so they may ask you to provide a notarized note, it should have all your parents info, contact numbers address, as well as state that yes you have their permission to travel to Canada for this period time, state the dates you will be gone, where you will be staying, who you are with or staying with, when you are expected back. The link below is the Canadian Version of the letter but it will give you an idea of what it needs to include. 2nd Link is the US Border Patrol info on minors traveling with out their parents. As for ID you will need a passport at that time for any mode of travel, effective June 1/2009 all travelers will require a passport.
