My 15 year old daughter might be traveling to Canada alone?

My daughter is 15 and she has been dying to go to Canada for over 3 years now, but my boss might not let me off from work the days we had planned. I know a passport isn't required for border crossing by land, and I've heard that, since she's under 16, that no passport would be required for her to fly, only birth certificate, ID, and a note of consent from me. And I'd prefer not to have to get her one because they are very expensive and it take a long time to get it back.
So what do I do if I don't get my days off? Do I put her on a Greyhound with 3 cell phones and a help whistle? Or would I be able to put her on a plane with just the note, birth certificate, ID, etc.
With your answers, please list a reliable source. Thanks in advance.
Ah, I'm not an irresponsible parent, my daughter has a friend there and I've met her and her parents before and I'm sure she would be taken care of.
Besides, don't ask me why, just give me the answer I asked for, not your opinion.
Also, this is a "what if" question.
And I can't take sick days without being fired, thanks =)

first of all WHy? does she know someoe? family? have u met these people? otherwise ide say um hell no to her. she can go another time. she wont die if she odnt go. cant say she wont if she goes tho theres always a possibility

You need to go w/her. The legal age of consent to have SEX is 14. So, since your kid is 15, I think you'd better go. Take a sick day if you must. You may trust her, but do you trust all the guys in Canada? Not to scare you ,but think of Natalie Holloway, 18 and more than likely dead.

ok to make it short ... Hell no don't let her go alone.

(If you can't go..she shouldn't go..you may not like the answer.. but that's my blunt honest feelings about letting a minor going anywhere w/o a parent)

Where is she going in Canada, and where is she coming from? There are definately some places that I would not send my daughter alone....but there some that I might consider too (when she is 15 - maybe - she's only 10 now). I would do some research on the route that she would be taking on the bus and on the place where she is going before sending her...

First, yes, she has to have a passport to fly, regardless of age. The under 16 provision is only per land and sea crossings when that part of the law comes into effect Jan 2008.

Is train an option? That would sure be better than Greyhound. If you do choose to let her take Greyhound (and I trust you know your daughter and her responsibility level enough to know if she is ready for that, or you wouldn't be considering it!), anyway, if she does, make sure you go over the safety rules, including sitting near the front of bus and staying in groups at stops.

U.S. cell phones may or may not work in Canada, depends on the phone and carrier.

The note allowing her to travel needs to be notarized. List the people she is meeting and staying with, as well as emergency numbers.

Blessings.
