Notarized Letter for my daughter...

Wow. He is being quite selfish. He's probably upset that you're not begging for him back and that you're going on the trip. I would do as the ladies mention, and find out if you do not his a letter from him... for just incase reasons that he pulls another fast one again. And you're right he was the one that ended everything, so he has no right to be doing what he is doing to you.

i work for an airline that flies from canada to mexico, and as of the last few years there is no letter of consent required for minors traveling with one parent/someone other than a parent.

as long as you have the childs passport that is all that is needed.

also, besides that i see dozens of kids every day traveling to mexico with only one parent, for personal measure, we take my husbands kids to mexico all the time and a few years ago we did have to get a notarized letter from their mom but it is NOT required now.

ETA: i just went to look it up in our reference manual to get a direct quote, and it actually says "Effective 21DEC04, LOC (letters of consent) are no longer required for minors traveling to Mexico."

BUT as far as Immigration Canada is concerned, the airline will not deny travel to a customer without it when re-entering Canada, but Canada may detain the customer or deny entry.

it does say divorced parents should have proof of custody, and widowed parents must have a death cert, but nothing about single, unmarried parent with child.

ALL OF THE ABOVE PERTAINS TO entry or RE-ENTRY TO CANADA, not entry into mexico, fyi.

My best wishes to you, hoping some sort of peace in his heart will change his confused mind.

all the best from Mexico
