hi. what age can my son chose to live, with which parent
Canada has no specific law addressing this.
Depends if the parent has said that the child can choose what he wants, if the parent has then it is recommended that the child is given the choice of the school that they get to go to
When they are 18.
Under UK law, a child has no legal right to choose which parent they may live with.
yep, if you are over 12 then you can choose what parent to live with
There is no such process. A child of 12 is not allowed to choose.
A child can not do this so you have to be 18.

18.
No there is no need for the child to go to Texas.
